Question

The electric field strength at a point in an electric field is 30 N/C. Find the force experienced by a charge of 20 C at that point.

• A. 600 N
• B. 30 N
• C. 20 N
• D. 300 N

Hint:

The force on a charge in an electric field is directly proportional to the electric field strength and the charge.

Answer 1

The Correct Option is A

The force on a charge in an electric field is given by: \[ F = E \times q \] Where: - \( E = 30 \, \text{N/C} \) (electric field strength) - \( q = 20 \, \text{C} \) (charge) Now, calculate the force: \[ F = 30 \times 20 = 600 \, \text{N} \] Thus, the force experienced by the charge is 600 N.
