The de Broglie wavelength of a tennis ball of mass 60g moving with a velocity of `10 ms^(-1)` is approximate [Planck's constant `= 6.63 xx 10^(-34) J s`]

Options

A. `10^(-33) m`
B. `10^(-31) m`
C. `10^(-16)m`
D. `10^(-25) m`

Answer

A

Explanation

According to de Broglie relationship, `lamda =(h)/(mv) =(6.63xx10^(-34))/(60xx10^(-3)xx10)=1.15xx10^(-33) m`
