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

25

B

75

C

60

D

50

Text Solution

Verified by Experts

The correct Answer is:
B
KE = 16 times `rArr` V = 4 times
`rArr` De-broglie wavelength `(lamda = (h)/(mV))`
= on fourth `(lamda_(0)rarr(lamda_(0))/(4))`. So De-Broglie wave will decrease by 75 %.
