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

`0.1 kg`

B

`0.25 kg`

C

`0.15 kg`

D

`0.2 kg`

Text Solution

Verified by Experts

The correct Answer is:
A
`lambda = (h)/(mv)`
`:. 6.62 xx 10^(-35)m = (6.62 xx 10^(-34) kg m^(2))/(x xx 100 ms^(-1))`
`:. x = 0.1 kg`
