A particle having a mass of 1.0 mg has a velocity of 3600 k m / h . Calculate the wavelength of the particle.

Question

A particle having a mass of 1.0 mg has a velocity of 3600 k m / h . Calculate the wavelength of the particle., 6.626 × 10 - 31 m, 6.626 × 10 - 30 m, 6.626 × 10 - 29 m, 6.626 × 10 - 28 m

MARKS App · Accepted Answer

v = 3600 k m / h r = 1000 m / s p = m v = 1 × 10 - 6 k g 1000 m / s = 10 - 3 k g m / s Use de broglie's relation. λ = h / m v = 6.626 × 10 - 34 J - s 1 × 10 - 3 k g = 6.626 × 10 - 31 m
