Question

charge enters in uniform magnetic field gains ?
A: K.E
B: P.E
C:No energy
D: A and B Both

Answer 1

Answer:

Option D

Both kinetic energy and potential energy

Answer 2

ANSWER:

D: A and B Both

EXPLANATION:

   The most common case happens when a particle charged moves at a 90 degree to a uniform B-field and if the field's nature is vacuum filled then, the charged particle experiences both "kinetic and potential energy". As the "magnetic force is perpendicular" to the "direction of travel", a charged particle when the charged particles enter the magnetic field with circles around.

  There is another way to look at this is that the particle's motion is "always perpendicular" to the circle motion of the particle.
