The wavelength associated with a ball of mass 100 g moving with a speed of `10^(3)` cm `"sec"^(-1)` (`h=6.6xx10^(-34)Js^(-1)`) is

A

`6.6xx10^(32)cm`

B

`6.6xx10^(-27)cm`

C

`6.6xx10^(27)cm`

D

`6.6xx10^(-32)cm`

Text Solution

Verified by Experts

The correct Answer is:
D
`lamda=h/(mv)=(6.6xx10^(-34)kgms^(-1))/(100xx10^(-3)kgxx10^(3)xx10^(-2)ms^(-1))`
`=.6xx10^(-32)cm`
