A body of mass x g is moving with a velocity of 100m/s. It de Broglie wavelength is `6.62xx10^(-35)m`. Hence x is `(h=6.62xx10^(-34)J-s)`

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
`lamda=h/(mv)`
`6.62xx10^(-35)=(6.62xx10^(-34))/(x xx 100)`
or `x=10^(-1)kg=0.1kg`
