alleryStart learning →The SI unit of electric charge is the:
- volt
- ampere
- coulomb
- ohm
Show answer and solution
Correct answer: C. coulomb
Charge is measured in coulombs (C). 1 C = 1 A·s.
The fundamental unit of charge is e = 1.6 × 10⁻¹⁹ C (proton/electron magnitude).

The magnetic force on a charge q moving with velocity v in field B:
- qE
- qvB sin theta
- q²B
- qB/v
Show answer and solution
Correct answer: B. qvB sin theta
F = qv × B. Magnitude F = qvB sin theta where theta is angle between v and B. Direction perpendicular to both v and B.
