[SOLVED] A question about Magnetic Fields and A Charge
A charged particle enters in 90 degrees to the magnetic field i.e. the force on the charge is F = qvB as sin (angle) = 1. The question is which are the effects on the kinetic energy and momentum of the particle?
Alternatives:
A. KE => Changed
Momentum => Changed
B. KE => Unchanged
Momentum => Changed
The solution is B but I do not why? Please, help me.
