Sol:
Answer : (4)
Directions: Questions number 33-34 contain Statement-1 and Statement-2. Of the four choices given after the statements, choose the one that best describes t the two statements.
Q. 3. Statement-1: Two particles moving in the same direction do not lose all their energy in a completely 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 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
Sol:
By conservation of momentum, magnitude of momentum can not become zero.
So kinetic energy can not be lost completely
Answer : (1)
Q. 4. Statement-1: When ultraviolet light is incident on a photocell, its stopping potential is V0 and the maximum 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 value because of the range of frequencies present in the incident light.
