If the magnetic force is 3.5 × 10–2 N, how fast is the charge moving?

The velocity of charge is 1.1×10⁴

Option(D)

Explanation:

F = q(v×B)

3.5×10-²= (8.4×10-⁴)*(v)*(6.7×10-³)*sin35

v = (3.5)/(8.4×6.7×0.57) × 10⁵

v = 3.5/32.08 × 10⁵

v = 0.109 × 10⁵

v ≈ 1.1 × 10⁴ m/s

Took it on edg

answer: (431,2)

step-by-step explanation:

beta is electron from nucleus

something from nucleus has changed, but charge must be same for cons of charge
