Question

What is the dimension of electric flux?

(a) [M L^3 T^-3 I^-1]

(b) [M L^2 T^-3 I^-1]

(c) [M L^3 T^-3 I^1]

(d) [M L^3 T^3 I^-1]

This question was posed to me by my college director while I was bunking the class.

The doubt is from Electric Flux topic in division Charges and Fields of Physics – Class 12

Answer 1

Right option is (a) [M L^3 T^-3 I^-1]

The best I can explain: Electric flux=electric field intensity* area. The dimension of field intensity is [M L T^-3 I^-1] and the dimension of the area is [L^2]. Therefore, the dimension of flux = [M L^3 T^-3 I^-1]. This can also be justified that flux=potential*length. By putting the dimensions of potential and length, we can get the same result.
