Document Summary
Chapter-02: electrostatic potential and capacitance: electrostatic potential at a point: It is the work done by per unit charge by an external agency, in bringing a charge from infinity to that point: electrostatic potential due to a charge at a point: Q r: the electrostatic potential at a point with position vector r due to a point dipole of dipole moment p place at the origin is (cid:1)(cid:2) (cid:2) 2 p q n r np where r1p is the distance between q1, and p, as and so on: electrostatics potential energy stored in a system of charges: It is the work done (by an external agency) in assembling the charges at their locations: electrostatic potential energy of two charges q1, q2, at r1, r2: 12 where r12 is distance between q1 and q2: potential energy of a charge q in an external potential: V(r)= qv(r: potential energy of a dipole of dipole moment p in a uniform electric field:
