Find the de broglie wavelength of a ball of mass 0.20 kg just before it strikes the earth after being |dropped from a building 50 m tall. important: step by step *typed* format preferred. if hand written, write clearly and legibly. be sure answer is correct.

Wavelength of the ball is

Explanation:

It is given that,

Mass of the ball, m = 0.2 kg

It strikes the Earth after being dropped from a building of 50 m tall, h = 50 m

In this time, the potential energy is converted to kinetic energy. On applying the conservation of energy as :

.............(1)

The De-broglie wavelength of the ball is given by :

Hence, this is the required solution.

i guess it’s a and b
