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
Correct Answer: Option B
Explanation

F = qvB
= 10 x 10-6 x 1.0 x 105 x 10-4
= 5.0 x 10-4N
