Question

5. The force on a charged particle moving in a magnetic field is maximum when the angle between
direction of motion and field is: *
(1 Point)
90
45
180​

Answer 1

Answer.--- 90°

Explanation= As the formula of force on a moving charged particle in a magnetic field is

F=qvB sinQ.

(Where Q is the angle between the direction of motion & field.

Soi, the force is maximum when sin Q is max.

And when sinQ is max. Then Q=90° which is the reqd.answer
