A 10\(\mu\)C charge moves with a velocity of 1.0 x 105 ms-1 at right angle to a uniform magnetic field of flux density 5.0 x 10-4T. Calculate the force on the charge

A.

5.0 x 10-5N

B.

5.0 x 10-4N

C.

5.0 x 105N

D.

5.0 x 106N

View answer & explanation

Correct answer is B

F = qvB

= 10 x 10-6 x 1.0 x 105 x 10-4

= 5.0 x 10-4N
