The electric field intensity is defined as

Force per unit charge

Force on a test charge

Product of force and charge

Force per unit charge on a test charge

Correct Answer : Option (D) : Force per unit charge on a test charge

Explanation : The electric field intensity is the force per unit charge on a test charge, i.e, q1 = 1C. E = F/Q = Q/(4∏εr2).
