The following plot represents the de-Broglie wavelength as a function of the kinetic energy (K.E.) of two particles A and B. Identify the correct relation

Options

A. `m_A = m_B`
B. `m_A lt m_B`
C. `m_A gt m_B`
D. `m_A = m_B =0 `

Answer

C

Explanation

E = K.E `hcv = 1/2 mv^2" " h( c)/(lamda) = 1/2 mv^2`
As increasing mass of partical
slope of `lamda_(vs) sqrt( (1)/(K.E))` decreases
