Calculate the wavelength of a track star running `150` metre dash in `12.1 sec` if its weight is `50 kg`.

A

`9.11 xx 10^-34 m`

B

`8.92 xx 10^-37 m`

C

`1.12 xx 10^-45 m`

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
B
(b) `lamda = h //mv = (6.626 xx 10^-24)/(50 xx (150 //12)) = 8.92 xx 10^-37 m`.
