If the kinetic energy of the particle is...

If the kinetic energy of the particle is increased to `16` times its previous value , the percentage change in the de - Broglie wavelength of the particle is

A

60

B

50

C

25

D

75

Text Solution

Verified by Experts

The correct Answer is:
D
`lamda=h/p=h/(sqrt(2mE))`
`lamda.=lamda/4 = 0.25Å`
% Change = (100 - 25) = 75%.
