1Two point masses m1 = 1000 kg and m2 = 4000 kg are separated by a distance of r = 2.0 m in a vacuum. Using Newton's Law of Universal Gravitation (G = 6.674 x 10^-11 N m^2/kg^2), what is the magnitude of the gravitational force between them?
A.6.67 x 10^-5 N
B.1.33 x 10^-4 N
C.3.34 x 10^-5 N
D.2.67 x 10^-7 N
Explanation: The gravitational force is 6.67 x 10^-5 N. Applying Newton's law of universal gravitation: F = G * m1 * m2 / r^2 = (6.674 x 10^-11) * 1000 * 4000 / (2.0)^2 = (6.674 x 10^-11) * (4.0 x 10^6) / 4.0 = 6.674 x 10^-5 N.
2A spherical planet has mass M = 6.00 x 10^24 kg and radius R = 6.00 x 10^6 m. Using G = 6.674 x 10^-11 N m^2/kg^2, what is the surface gravitational field strength g?
A.6.67 N/kg
B.11.1 N/kg
C.9.80 N/kg
D.66.7 N/kg
Explanation: The surface gravitational field strength is 11.1 N/kg. Gravitational field strength is g = G * M / R^2 = (6.674 x 10^-11) * (6.00 x 10^24) / (6.00 x 10^6)^2 = (4.0044 x 10^14) / (3.60 x 10^13) = 11.12 N/kg.
3What is the weight of an astronaut with mass m = 70.0 kg on the Moon's surface, where local gravitational acceleration is g_moon = 1.62 m/s^2?
A.686 N
B.113 N
C.43.2 N
D.162 N
Explanation: The astronaut's weight on the Moon is 113 N. Weight is given by W = m * g_moon = 70.0 kg * 1.62 m/s^2 = 113.4 N.
4Two point charges q1 = +2.00 μC and q2 = +5.00 μC are separated by d = 0.100 m in air (k_e = 8.99 x 10^9 N m^2/C^2). What is the magnitude of the electrostatic repulsive force between them?
A.0.899 N
B.8.99 N
C.89.9 N
D.4.49 N
Explanation: The electrostatic repulsive force is 8.99 N. By Coulomb's Law: F = k_e * |q1 * q2| / d^2 = (8.99 x 10^9) * (2.00 x 10^-6) * (5.00 x 10^-6) / (0.100)^2 = (8.99 x 10^-2) / 0.0100 = 8.99 N.
5What is the electric field magnitude E at distance r = 0.200 m from a point charge q = +4.00 nC in a vacuum (k_e = 8.99 x 10^9 N m^2/C^2)?
A.179.8 N/C
B.899 N/C
C.449.5 N/C
D.3596 N/C
Explanation: The electric field magnitude is 899 N/C. Electric field intensity is E = k_e * q / r^2 = (8.99 x 10^9) * (4.00 x 10^-9) / (0.200)^2 = 35.96 / 0.0400 = 899 N/C.
6What is the electric potential V at distance r = 0.500 m from a isolated point charge q = +10.0 nC in a vacuum (k_e = 8.99 x 10^9 N m^2/C^2)?
A.179.8 V
B.359.6 V
C.89.9 V
D.17.98 V
Explanation: The electric potential is 179.8 V. Electric potential is V = k_e * q / r = (8.99 x 10^9) * (10.0 x 10^-9) / 0.500 = 89.9 / 0.500 = 179.8 V.
7A charge q = +3.00 μC moves with speed v = 200 m/s perpendicular to a uniform magnetic field B = 0.500 T. What is the magnitude of the magnetic Lorentz force acting on the charge?
A.3.00 x 10^-4 N
B.6.00 x 10^-4 N
C.1.50 x 10^-4 N
D.3.00 x 10^-1 N
Explanation: The magnetic Lorentz force is 3.00 x 10^-4 N. Lorentz force for perpendicular motion is F = |q| * v * B * sin(90°) = (3.00 x 10^-6 C) * (200 m/s) * (0.500 T) * 1.0 = 3.00 x 10^-4 N.
8What is the magnetic field strength B at distance r = 0.050 m from an infinitely long straight wire carrying electric current I = 10.0 A in a vacuum (μ0 = 4π x 10^-7 T m/A)?
A.4.00 x 10^-5 T
B.2.00 x 10^-5 T
C.8.00 x 10^-5 T
D.1.26 x 10^-4 T
Explanation: The magnetic field strength is 4.00 x 10^-5 T. By Ampère's Law / Biot-Savart Law: B = μ0 * I / (2π * r) = (4π x 10^-7 * 10.0) / (2π * 0.050) = (2 x 10^-6) / 0.050 = 4.00 x 10^-5 T.
9A planar loop of area A = 0.020 m^2 is placed perpendicular to a uniform magnetic field B = 0.400 T (angle θ = 0° between field and surface normal). What is the magnetic flux Φ through the loop?
A.8.00 x 10^-3 Wb
B.1.60 x 10^-2 Wb
C.4.00 x 10^-3 Wb
D.0 Wb
Explanation: The magnetic flux through the loop is 8.00 x 10^-3 Wb. Magnetic flux is Φ = B * A * cos(θ) = 0.400 T * 0.020 m^2 * cos(0°) = 8.00 x 10^-3 Wb.
10A mass undergoes simple harmonic motion with amplitude A = 0.050 m and angular frequency ω = 10.0 rad/s. What is its maximum speed v_max?
A.0.500 m/s
B.5.00 m/s
C.0.050 m/s
D.0.250 m/s
Explanation: The maximum speed is 0.500 m/s. In simple harmonic motion, maximum speed occurs at equilibrium (x = 0) and is v_max = ω * A = 10.0 rad/s * 0.050 m = 0.500 m/s.
