Question

An alpha-paricle, a deuteron and a proton are moving with same momentum in a
uniform magnetic field. The ratio of their speeds will be​

Answer 1

Answer:

given:

momentum for these particle are same

let the mass of protons be m

mass of deutron = 2m

mass of alpha part.= 4m

p of alpha part. = 4mv1 => v1 = p/4 m

p of deutron = 2mv2 => v2 = p/2m

p of protons = mv3 => v3 = p/ m

v1:v2:v3=1:2:4
