Question

a point charge of 5.0 × 10–7 c moves to the right at 2.6 × 105 m/s in a magnetic field that is directed into the screen and has a field strength of 1.8 × 10–2 t. what is the magnitude of the magnetic force acting on the charge?

Answer 1

When a charge moves in a magnetic field, the magnitude of the magnetic force acting on the charge is 2.34 kN.

What is magnetic field?

The magnetic field is the region of space is where a charged particle experiences the magnetic force.

The magnetic force is the product of charge, velocity and field strength.

F = q x v x B

Given is a point charge of 5.0 × 10⁻⁷ C moves to the right at 2.6 × 10⁵ m/s in a magnetic field that is directed into the screen and has a field strength of 1.8 × 10⁻² T.

Substituting the values into the magnetic force expression, we get

F =  5 x 10⁻⁷ x 2.6 × 10⁵ x 1.8 x 10⁻²

F = 2.34 x 10⁻³ N

F = 2.34 kN

Thus, the magnitude of the magnetic force acting on the charge is 2.34 kN.
