In which of the following conditions the de Broglie wavelentgh of particle A will be less than that of particle B `(m_(A) gt m_(B))` ?

Options

A. Linear momentum of these particles are same
B. Move with same speed
C. Move with same kinetic energy
D. Have fallen through same height

Answer

B, D

Explanation

`lambda = h/(mupsilon) `, for same speed,
`lambda_A lt lambda_B ` because `m_A gt m_B`.
