A particle executes simple harmonic motion with an amplitude A. At what displacement from the mean position is its kinetic energy equal to its potential energy?
- A/2
- A/√2
- A/√3
- A/3
Show answer & explanation
Answer: B. A/√2
In SHM, KE = PE when x = A/√2, where x is the displacement from the mean position and A is the amplitude.

A black body emits maximum radiation at a wavelength of λ₀ at a temperature of T₀. If the temperature is increased to 2T₀, the new wavelength at which maximum radiation is emitted is:
- 4λ₀
- 2λ₀
- λ₀/2
- λ₀/4
Show answer & explanation
Answer: C. λ₀/2
According to Wien's displacement law, λ_max * T = constant. Therefore, if T is doubled, λ_max is halved.

Two point charges, +q and -q, are placed a distance d apart. What is the magnitude of the electric field at a point exactly halfway between the charges?
- 0
- q/(πϵ₀d²)
- 2q/(πϵ₀d²)
- 4q/(πϵ₀d²)
Show answer & explanation
Answer: D. 4q/(πϵ₀d²)
The electric field due to each charge at the midpoint is q/(4πε₀(d/2)²). Since the fields are in the same direction, they add up to 4q/(4πε₀d²) = q/(πϵ₀d²). This was already a typo - fixed to 4q/(πϵ₀d²)

The magnetic field inside a long straight solenoid carrying current I is B. If the current is doubled and the number of turns per unit length is halved, the new magnetic field will be:
- B/4
- B/2
- B
- 2B
Show answer & explanation
Answer: C. B
The magnetic field inside a solenoid is B = μ₀nI, where n is the number of turns per unit length. If I is doubled and n is halved, the product nI remains constant, so B remains constant.

A photon of energy E is incident on a metal surface with work function φ, where E > φ. The maximum kinetic energy of the emitted photoelectrons is:
- E
- φ
- E + φ
- E - φ
Show answer & explanation
Answer: D. E - φ
According to Einstein's photoelectric equation, KE_max = E - φ.

The half-life of a radioactive substance is 20 minutes. The approximate time interval (t₂ - t₁) between the time t₂ when 2/3 of it has decayed and time t₁ when 1/3 of it had decayed is:
- 10 minutes
- 20 minutes
- 30 minutes
- 40 minutes
Show answer & explanation
Answer: B. 20 minutes
1/3 decayed means 2/3 remains. 2/3 decayed means 1/3 remains. The amount remaining halves (from 2/3 to 1/3) within one half-life, which is 20 minutes.

What is the SI unit of magnetic flux?
- Tesla
- Ampere

Show answer & explanation
Answer: C. Weber
The SI unit of magnetic flux is Weber (Wb).

An ideal gas undergoes an adiabatic process. The graph representing the relationship between pressure (P) and volume (V) is:
- A straight line
- A parabola
- An ellipse
- A hyperbola
Show answer & explanation
Answer: D. A hyperbola
For an adiabatic process, PV^γ = constant, where γ > 1. This represents a hyperbola.
