1What is the dimensional formula of Planck's constant (h)?
A.[M L^2 T^-1]
B.[M L^2 T^-2]
C.[M L T^-1]
D.[M L^2 T^-3]
Explanation: Planck's constant is defined by the energy equation E = hν. Since frequency ν has dimensions [T^-1] and energy E has dimensions [M L^2 T^-2], the dimensional formula of h is [M L^2 T^-2] / [T^-1] = [M L^2 T^-1]. This is equivalent to the dimensions of angular momentum.
2Which of the following physical quantities is a direct quantitative measure of the inertia of a body?
A.Velocity
B.Acceleration
C.Mass
D.Force
Explanation: Inertia is the inherent property of a body by virtue of which it opposes any change in its state of rest or uniform motion. Mass is the direct quantitative measure of this inertia; a body with larger mass requires more force to achieve a given acceleration.
3If the momentum of a body of mass m is doubled, by what factor does its kinetic energy increase?
A.2 times
B.4 times
C.8 times
D.Remain unchanged
Explanation: The relationship between kinetic energy (K) and momentum (p) is K = p^2 / (2m). Since kinetic energy is directly proportional to the square of momentum, doubling the momentum (p' = 2p) results in K' = (2p)^2 / (2m) = 4K, an increase of 4 times.
4What is the value of the acceleration due to gravity (g) at the center of the Earth?
A.9.8 m/s^2
B.Infinite
C.Zero
D.Same as that at the poles
Explanation: The acceleration due to gravity at depth d below the Earth's surface is g_d = g(1 - d/R), where R is the Earth's radius. At the center of the Earth, d = R, which yields g_c = g(1 - 1) = 0. The gravitational forces from all directions cancel out.
5Two point charges placed at a distance r in air exert a force F on each other. If they are placed at the same distance in a medium of dielectric constant K, what will be the force between them?
A.F * K
B.F / K
C.F / K^2
D.F
Explanation: Coulomb's Law states that force in a medium of dielectric constant K is given by F' = 1/(4πε) * q1*q2/r^2 = F/K. The polarization of the dielectric medium creates an opposing electric field that reduces the net electrostatic force.
6How does the electrical resistance of a metallic conductor change when its temperature increases?
A.Decreases linearly
B.Increases
C.Remains constant
D.Decreases exponentially
Explanation: As the temperature of a metal increases, thermal vibrations of lattice ions increase. This leads to more frequent collisions of conduction electrons with the lattice, reducing the relaxation time (τ). Since resistance is inversely proportional to relaxation time, resistance increases.
7What is the speed of light in a glass medium of refractive index 1.5, given that the speed of light in vacuum is 3.0 * 10^8 m/s?
A.2.0 * 10^8 m/s
B.4.5 * 10^8 m/s
C.1.5 * 10^8 m/s
D.3.0 * 10^8 m/s
Explanation: The refractive index (n) of a medium is defined as n = c / v, where c is the speed of light in vacuum and v is the speed in the medium. Rearranging gives v = c / n = (3.0 * 10^8 m/s) / 1.5 = 2.0 * 10^8 m/s.
8In the photoelectric effect, what is the minimum frequency of incident radiation below which no photoelectron emission occurs called?
A.Resonant frequency
B.Threshold frequency
C.Critical frequency
D.Cut-off frequency
Explanation: The threshold frequency (ν0) is the minimum frequency of incident light required to eject electrons from a metal surface. Photons with frequency below this value do not have enough energy to overcome the metal's work function, regardless of intensity.
9What are the majority charge carriers in a p-type semiconductor?
A.Electrons
B.Holes
C.Protons
D.Neutrons
Explanation: A p-type semiconductor is created by doping a tetravalent semiconductor (like Silicon) with trivalent impurities (like Boron). This creates a deficiency of valence electrons, resulting in holes which act as the majority charge carriers.
10What is the expression for the maximum height (H) attained by a projectile fired with an initial velocity u at an angle θ with the horizontal?
A.H = (u^2 * sin(2θ)) / g
B.H = (u^2 * sin^2(θ)) / (2g)
C.H = (u^2 * sin^2(θ)) / g
D.H = (u * sin(θ)) / g
Explanation: For a projectile, the vertical component of initial velocity is u_y = u sinθ. At the maximum height, vertical velocity is zero. Using v_y^2 = u_y^2 - 2gH gives 0 = (u sinθ)^2 - 2gH, which simplifies to H = (u^2 sin^2θ) / (2g).
