A body of mass x kg is moving with a velocity of `100ms^(-1)` . Its de-Broglie wavelength is `6.62xx10^(-35)m` . Hence, x is: `(h=6.62xx10^(-34)Js)`

A

0.25 kg

B

0.15 kg

C

0.2 kg

D

0.1 kg

Text Solution

Verified by Experts

The correct Answer is:
D
According to de-Broglie's equation , `lambda =h/"mv" rArr 6.62xx10^(-35) =(6.62xx10^(-34)) /(x xx 100) rArr x =0.1 kg `
