Question

The work done in moving a point charge of $10\mu C$ through a distance of $3 \,cm$ along the equatorial axis of an electric dipole is

• A. $10 \times 10^{-6}\,J$
• B. $30 \times 10^{-6}\,J$
• C. $20 \times 10^{-6}\,J$
• D. $5 \times 10^{-6}\,J$
• E. zero

Answer 1

Answer: (E)

Electrostatic potential is zero along the equatorial line of the dipole
