Question

A (-8.8×10-20 C) charge is moving at (9.6×106 m/s) perpendicular a magnetic field. It
experiences a force of to (-5.2×10-16 N). What is the magnetic field strength?

6.2×10 -4 T
5.4×10 -15 T
3.2 ×10 -27 T
4.4×10 -20 T

Answer 1

The magnetic field strength will be 6.1 x 10⁻⁴ T.

What is magnetic field?

The magnetic field is the region of space where a charged object experiences magnetic force when it is moving.

The magnetic field strength is the magnitude of magnetic field in Tesla. It is related to velocity, magnitude of charge and force by the relation,

Magnetic force F = qVB

Given is the charge q = -8.8×10⁻²⁰ C, Force F = -5.2×10⁻¹⁶ N and the velocity v = 9.6×10⁶ m/s, then the magnetic field strength will be

B =  -5.2×10⁻¹⁶/-8.8×10⁻²⁰ x9.6×10⁶

B = 6.1 x 10⁻⁴ T

Thus, the magnetic field strength will be 6.1 x 10⁻⁴ T.
