Answer:
3.8 N
Explanation:
The force, F exerted on a charge q moving with a velocity, v in a magnetic field of strength, B is F = Bqv
Given that B = 3.0 × 10² T , q = 2.5 μC = 2.5 × 10⁻⁶ C and v = 5.0 × 10³ m/s.
So, F = Bqv = 3.0 × 10² T × 2.5 × 10⁻⁶ C × 5.0 × 10³ m/s = 37.5 × 10⁻¹ N = 3.75 N
F = 3.75 N ≅ 3.8 N
