BITSAT Physics Question (2023) — Solution

Question

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

  1. A. Nm ^3 C ^ -1 ; Nm ^2 C ^ -1
  2. B. Nm ^2 C ^ -1 ; Nm ^3 C ^ -1
  3. C. Nm ^3 C ; Nm ^2 C
  4. D. Nm ^2 C ; Nm ^3 C

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
