Electric field in a certain region is given by E = ( A x^2 i + B y^3 j ) . The SI unit of A and B are:
Options
- ANm ^3 C ⁻¹ ; Nm ^2 C ⁻¹
- BNm ^2 C ⁻¹ ; Nm ^3 C ⁻¹
- CNm ^3 C ; Nm ^2 C
- DNm ^2 C ; Nm ^3 C
Correct answer
B. Nm ^2 C ⁻¹ ; Nm ^3 C ⁻¹
Step-by-step solution
Electric field in a certain region is given by, E = A x^2 i + B y^3 j [ A x ^2 ]= NC ⁻¹ [ A ]= Nm ^2 C ⁻¹ [ B y ^3 ]= NC ⁻¹ [ B ]= Nm ^3 C ⁻¹
