SATHEE: Atomic Structure Question 175

Atomic Structure Question 175

Question: A 200g golf ball is moving with a speed of 5 m per hour. The associated wave length is $(h = 6.625 \times 10^{- 34} J - s e c)$

Options:

A) $10^{- 10}, m$

B) $10^{- 20}, m$

C) $10^{- 30}, m$

D) $10^{- 40}, m$

Show Answer

Answer:

Correct Answer: C

Solution:

$λ = \frac{h}{m v} = \frac{6.625 \times 10^{- 34}}{0.2, k g \times \frac{5}{60 \times 60, m s^{- 1}}} = 10^{- 30} m$ .
