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

Electric field in a certain region is given by, E = x 2 A i ^ + y 3 B j ^ [ x 2 A ] = NC − 1 ⇒ [ A ] = Nm 2 C − 1 [ y 3 B ] = NC − 1 ⇒ [ B ] = Nm 3 C − 1

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

Options:

Answer:

Solution:

Electric field in a certain region is given by,
$E = \frac{A}{x ^{2}} \hat{i} + \frac{B}{y ^{3}} \hat{j}$
$[\frac{A}{x ^{2}}] = NC^{- 1} \Rightarrow [A] = Nm^{2} C^{- 1}$
$[\frac{B}{y ^{3}}] = NC^{- 1} \Rightarrow [B] = Nm^{3} C^{- 1}$
