Question

When a particle carrying a charge of 100 µC moves at an angle of 30° to a uniform magnetic field of induction 6 x 10^-5 Wb/m² with a speed of 2 x 10⁵ m/s. The force acting on the particle is ______

Options

• 6 x 10^-4 N

• 10^-3 N

• 2 x 10^-4 N

• 10^-4 N

Answer 1

When a particle carrying a charge of 100 µC moves at an angle of 30° to a uniform magnetic field of induction 6 x 10^-5 Wb/m² with a speed of 2 x 10⁵ m/s. The force acting on the particle is 6 x 10^-4 N.

Explanation:

F = qvB sinθ

= `100 xx 10^-6 xx 2 xx 10^5 xx 6 xx 10^-5 xx sin 30^circ`

F = `6 xx 10^-4` N
