A body of mass 10 g is moving with a velocity of 100ms−1100ms^{- 1}. The wavelength associated with it is.

A

6.626×10−7m6.626 \times 10^{- 7}m

B

6.626×10−34m6.626 \times 10^{- 34}m

C

6.626×10−4m6.626 \times 10^{- 4}m

D

6.626×10−35m6.626 \times 10^{- 35}m

Answer

6.626×10−34m6.626 \times 10^{- 34}m

Explanation

Solution

: λ=hmv=6.626×10−34Js0.01kg×100ms−1=6.626×10−34m\lambda = \frac{h}{mv} = \frac{6.626 \times 10^{- 34}Js}{0.01kg \times 100ms^{- 1}} = 6.626 \times 10^{- 34}m
