CHAPTER 2

 Electric Potential

1. 1. Define electric potential. Is it a vector or a scalar quantity?
   2. Draw two equipotentials due to a point charge.
   3. Draw an equipotential surface for a point charge Q > 0
   4. What would be the work done if a point charge +q, is taken from a point A to the point B on the circumference of a circle drawn with another point charge +q at the centre?
   5. Derive the expression for the electric potential at a distance ‘r’ from a point charge ‘Q’.
   6. What is an equipotential surface? Show that the electric field at a point on the surface of a charged conductor or just outside it is perpendicular to the surface?
   7. Potential due to dipole on axial and equatorial line
