b) accelerate a charge
c) change the momentum of a charge
d) change the kinetic energy of a charge
e) none of the above
Homework Answers
force due to static magnetic field,
F = q (v X B)
so Force will be always be perpendicular to the velocity.
And work done by perpendicular force will be zero.
from work - energy theorem,
Work done = change ih KE = 0
Ans(d) change the KE of charge
