An electric dipole is placed as shown in the figure. The electric potential (in 10 2   V ) at point P due to the dipole is ( ε 0 =permittivity of free space and 1 4 π ε 0 = K )

Options

  1. A8 3 q K
  2. B3 8 q K
  3. C5 8 q K
  4. D8 5 q K

Correct answer

B. 3 8 q K

Step-by-step solution

The net electric potential at P can be calculated as follows- V p = K q 5   cm - 3   cm × 1   m 10 2   cm - K q 5   cm + 3   cm × 1   m 10 2   cm = K q × 10 2 × 1 2 - 1 8 = 3 K q 8 × 10 2   V
