11. What is the dimension of electric field intensity? a) [M L T-2 I-1] b) [M L T-3 I-1] c) [M L T-2 I-2] d) [M L T-3 I]
Answer: b Explanation: Electric field intensity is defined as the force on a unit positive charge kept in an electric field. Hence we can simply consider its dimension asthedimensionofforcethedimensionofcharge. The dimension of force is [MLT-2] and the dimension of charge is [IT]. Therefore the dimension of field intensity is [M L T-3 I-1].
