Question

If the electric field strength due to a charged sphere at a point is 3 N/C, then find the force acting on a charge of 2C placed at that point.

  1. 2N
  2. 3N
  3. 6N
  4. 1.5N

hintHint:

F= qE

The correct answer is: 6N


    • The electric force on a particle is given by F= qE.
    • q= charge, E= electric field strength.
    • Given that E= 3N/C, q= 2C.
    • F= 2×3= 6N.
    • So, the force acting on the charge will be 6N.

    The electric force ___________ on the medium between the charges.

    • K= 1/4πε
    • The value of k depends on the electric permittivity of the medium (ε).
    • And the electric permittivity of a medium (ε) depends on the nature of the medium.
    • Therefore, the value of K is different for different medium.
    • Hence, the electrostatic force depends on the medium between the two charges.
