Question

The specific charge of a steady electron is 1.76 101 C/kg. If it move with velocity v =
с/2
(where c = velocity of light) then its specific charge is
C kg-1

Answer 1

first check attachment

Explanation:

specific charge of electron =charge/mass

=e/m

given e/m=1.76101 c/kg=S

mass of electron at c/2 speed =2m/under root 3

new specific charge=e/(2m/under root 3)

=root 3×e/2m

=(root 3)/2 ×S

=(root 3)/2×1.76101

required specific charge approximately =1.52c/kg
