Two particles A and B having charges of + 2.00 × 10-6 C and of -4.00 × 10-6 C respectively are held fixed at a separation of 20.0 cm. Locate the point(s) on the line AB where (a) the electric field is zero (b) the electric potential is zero.
44. A circular wire-loop of radius α carries a total charge Q distributed uniformly over its length. A small length dL of the wire is cut off. Find the electric field at the centre due to the remaining wire.
