The de-Broglie wavelength of a tennis ball of mass 60g moving with a velocity of 10 `ms^(-1)` is approximately (planck's constant, `h = 6.63 xx 10^(-34)` Js)

A

`10^(-33)` m

B

`10^(-31)` m

C

`10^(-16)` m

D

`10^(-25)` m

Text Solution

Verified by Experts

The correct Answer is:
A
`lambda = (h)/(mv) = (6.63 xx 10^(-34))/(60 xx 10^(-3) xx 10) ~~ 10^(-33) m`
