the charges when q1q2R and r< R.

13. Derive an expression for the torque experienced by an electric dipole kept in a uniform electric

field. Write the pair of vectors perpendicular to each other.

14. Using Gauss theorem, obtain the expression for the electric field due to uniformly charged linear

conductor.
