Electric field in a certain region is given by $\vec{E} = (\frac{A}{x^{2}} \hat{i} + \frac{B}{y^{3}} \hat{j}) . The SI unit of A and B$ are :

Accepted Answer

$\vec{E} = (\frac{A}{x^{2}} \hat{i} + \frac{B}{y^{3}} \hat{j})$

$[\frac{A}{x^{2}}] = [E] = [\frac{F}{q}] = [\frac{N}{C}] = N C^{- 1}$

$[A] = (N m^{2} C^{- 1})$

$[B] = N m^{3} C^{- 1}$
