1Two point masses of m1 = 2000 kg and m2 = 5000 kg are separated by a distance of r = 5.0 m in a vacuum. Using Newton's Law of Universal Gravitation with G = 6.67 x 10^-11 N m^2/kg^2, what is the magnitude of the gravitational force between them?
A.1.33 x 10^-4 N
B.5.34 x 10^-6 N
C.2.67 x 10^-7 N
D.2.67 x 10^-5 N
Explanation: Applying Newton's law of universal gravitation: F = G * m1 * m2 / r^2 = (6.67 x 10^-11) * (2000) * (5000) / (5.0)^2 = (6.67 x 10^-11) * (1.0 x 10^7) / 25 = 2.668 x 10^-5 N.
2If the gravitational field strength at Earth's surface is g0 = 9.80 N/kg, what is the field strength g at an altitude h = 2 R_E above Earth's surface, where R_E is Earth's radius?
A.3.27 N/kg
B.2.45 N/kg
C.4.90 N/kg
D.1.09 N/kg
Explanation: The distance from Earth's center is r = R_E + h = R_E + 2 R_E = 3 R_E. Since g = G M_E / r^2, g = G M_E / (3 R_E)^2 = g0 / 9 = 9.80 / 9 = 1.089 N/kg.
3A satellite moves in a circular orbit around Earth at an altitude h = R_E equal to Earth's radius (R_E = 6.37 x 10^6 m). Taking g0 = 9.80 m/s^2 at the surface, what is the satellite's orbital speed?
A.5.59 km/s
B.11.2 km/s
C.3.95 km/s
D.7.91 km/s
Explanation: At radial distance r = 2 R_E, centripetal force equals gravitational force: m v^2 / r = G M_E m / r^2 => v = sqrt(G M_E / r) = sqrt(g0 R_E^2 / (2 R_E)) = sqrt(g0 R_E / 2) = sqrt(9.80 * 6.37 x 10^6 / 2) = sqrt(3.1213 x 10^7) = 5587 m/s = 5.59 km/s.
4Given the Moon's mass M_M = 7.35 x 10^22 kg and radius R_M = 1.74 x 10^6 m, what is the escape velocity from the lunar surface? (G = 6.67 x 10^-11 N m^2/kg^2)
A.2.37 km/s
B.3.35 km/s
C.4.74 km/s
D.1.68 km/s
Explanation: Escape velocity is v_esc = sqrt(2 G M / R) = sqrt(2 * 6.67 x 10^-11 * 7.35 x 10^22 / 1.74 x 10^6) = sqrt(5.6356 x 10^6) = 2374 m/s = 2.37 km/s.
5What is the gravitational potential energy of a 500 kg satellite in a circular orbit of radius r = 1.28 x 10^7 m around Earth? (M_E = 5.97 x 10^24 kg, G = 6.67 x 10^-11 N m^2/kg^2)
A.-3.11 x 10^10 J
B.-7.78 x 10^9 J
C.+1.56 x 10^10 J
D.-1.56 x 10^10 J
Explanation: Gravitational potential energy is E_p = -G M_E m / r = -(6.67 x 10^-11 * 5.97 x 10^24 * 500) / (1.28 x 10^7) = -(1.991 x 10^17) / (1.28 x 10^7) = -1.555 x 10^10 J.
6Planet A orbits a star with radius r_A and orbital period T_A = 1.0 year. Planet B orbits the same star at a radius r_B = 4.0 r_A. According to Kepler's Third Law, what is planet B's orbital period?
A.4.0 years
B.16.0 years
C.8.0 years
D.2.0 years
Explanation: Kepler's Third Law states T^2 / r^3 = constant. Thus (T_B / T_A)^2 = (r_B / r_A)^3 = 4.0^3 = 64. Taking square roots gives T_B / T_A = 8.0, so T_B = 8.0 years.
7What is the total mechanical energy of a satellite of mass m = 1000 kg orbiting Earth in a circular path of radius r = 2.0 x 10^7 m? (M_E = 5.97 x 10^24 kg, G = 6.67 x 10^-11 N m^2/kg^2)
A.-4.98 x 10^9 J
B.-9.95 x 10^9 J
C.-1.99 x 10^10 J
D.+9.95 x 10^9 J
Explanation: Total mechanical energy of a circular orbit is E = K + E_p = -G M_E m / (2 r) = -(6.67 x 10^-11 * 5.97 x 10^24 * 1000) / (2 * 2.0 x 10^7) = -3.982 x 10^17 / 4.0 x 10^7 = -9.955 x 10^9 J.
8At what distance from Earth's center along the Earth-Moon line is the net gravitational field intensity equal to zero? (Earth mass M_E = 81 M_M, distance D between centers = 3.84 x 10^8 m)
A.3.46 x 10^8 m
B.1.92 x 10^8 m
C.3.07 x 10^8 m
D.3.70 x 10^8 m
Explanation: Setting field magnitudes equal: G M_E / x^2 = G M_M / (D - x)^2 => 81 / x^2 = 1 / (D - x)^2. Taking square roots: 9 / x = 1 / (D - x) => 9 D - 9 x = x => 10 x = 9 D => x = 0.9 D = 0.9 * 3.84 x 10^8 = 3.456 x 10^8 m.
9What is the orbital radius of a geostationary satellite around Earth with period T = 24 hours (86,400 s)? (M_E = 5.97 x 10^24 kg, G = 6.67 x 10^-11 N m^2/kg^2)
A.4.22 x 10^7 m
B.3.58 x 10^7 m
C.6.37 x 10^6 m
D.1.28 x 10^8 m
Explanation: Using Kepler's Third Law r^3 = G M_E T^2 / (4 pi^2) = (6.67 x 10^-11 * 5.97 x 10^24 * 86400^2) / (39.478) = 2.973 x 10^24 / 39.478 = 7.53 x 10^22 m^3. Taking cube root: r = 4.22 x 10^7 m (42,200 km).
10What altitude above Earth's surface corresponds to a geostationary orbit? (Earth radius R_E = 6.37 x 10^6 m, geostationary radius r = 4.22 x 10^7 m)
A.4.22 x 10^7 m
B.3.58 x 10^7 m
C.2.58 x 10^7 m
D.1.79 x 10^7 m
Explanation: Altitude h is the distance from Earth's surface: h = r - R_E = 4.22 x 10^7 m - 0.637 x 10^7 m = 3.583 x 10^7 m (35,830 km).

PAU Physics (Aragón): Suggested Study Strategy

1Master vector notation and signs for gravitational and electric fields, ensuring you correctly determine field direction and potential scalar values.
2Memorize key physical constants (G = 6.67 x 10^-11 N m^2/kg^2, c = 3.00 x 10^8 m/s, e = 1.60 x 10^-19 C, h = 6.63 x 10^-34 J s).
3Practice multi-step orbital calculations including escape velocity, satellite speed, energy conservation, and Kepler's third law (T^2/r^3).
4Understand the direction of induced current using Lenz's law ('nature opposes change in flux') and apply Faraday's law (EMF = -dPhi/dt).
5Become proficient in Snell's law (n1 sin theta1 = n2 sin theta2) and calculating critical angles for total internal reflection (sin theta_c = n2/n1).
6For optics, strictly follow sign conventions for focal length and distances when using the thin lens equation (1/f = 1/s' - 1/s or 1/f = 1/d_o + 1/d_i).
7Master photoelectric effect equations: E_photon = hf = W_0 + E_k,max, and understand stopping potential (E_k,max = e V_s).
8Calculate mass defect Delta m = [Z m_p + (A-Z) m_n] - m_nucleus and binding energy E_b = Delta m * c^2 accurately, converting between atomic mass units (u) and MeV.
