Answer:B
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]
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 as\(\frac {the \, dimension \, of \, force}{the \, dimension \, of \, charge}\). 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].
