Question

A 200g golf ball is moving with a speed of $5m$ per hour. The associated wave length is ball is moving with a speed of $5m$ per hour. The associated wave length is

• A. 10^-10 m
• B. 10^-20 m
• C. 10^-30 m
• D. 10^-40 m

Answer 1

The correct option is C

Given

Mass of golf ball = 200g

Speed of golf ball $\left(v\right)$ = 5 m/ hr

To find

The wavelength associated with golf ball ($\lambda$ ) =

$\lambda =\frac{h}{mv}=\frac{6.625\times {10}^{-34}}{0.2kg\times \frac{5}{60\times 60m{s}^{-1}}}={10}^{-30}m$

Conclusive statement - Option (C) is correct
