### Sample Questions

Question 1
If a source of power 4 kW produces 1020 photons/second, the radiation belong to a part of the spectrum called
 X–rays γ –rays microwaves ultraviolet rays
Question 2
A diatomic ideal gas is used in a Car engine as the working substance. If during the adiabatic expansion part of the cycle, volume of the gas increases from V to 32V the efficiency of the engine is
 0.5 0.25 0.99 0.75
Question 3
Statement-1: When ultraviolet light is incident on a photocell, its stopping potential is V0 and themaximum kinetic energy of the photoelectrons is Kmax . When the ultraviolet light is replaced by X-rays, both V0 and Kmax increase. Statement-2: Photoelectrons are emitted with speeds ranging from zero to a maximum valuebecause of the range of frequencies present in the incident light
 Statement-1 is true, Statement-2 is true; Statement-2 is the correct explanation of Statement-1 Statement-1 is true, Statement-2 is true; Statement-2 is not the correct explanation of Statement-1. Statement-1 is false, Statement-2 is true Statement-1 is true, Statement-2 is false.
Question 4
Statement-1 : Two particles moving in the same direction do not lose all their energy in acompletely inelastic collision. Statement-2 : Principle of conservation of momentum holds true for all kinds of collisions.
 Statement-1 is true, Statement-2 is true; Statement-2 is the correct explanation of Statement-1. Statement-1 is true, Statement-2 is false. Statement-1 is false, Statement-2 is true Statement-1 is true, Statement-2 is true; Statement-2 is not the correct explanation of Statement-1
Question 5
Let C be the capacitance of a capacitor discharging through a resistor R. Suppose t1 is the time taken for the energy stored in the capacitor to reduce to half its initial value and t2 is the time taken for the charge to reduce to one-fourth its initial value. Then the ratio t1 /t2 will be
 1 1/4 2 1/2
