Three charges -q,+2q, and -q are arranged on a line as shown in fig. Calculate the field at a distance rgtgta on the line.
There are four point charges +q, -q, +q and -q are placed at the corners A, B, C and D respectively of a square of side a . The potential energy of the system is (1)/(4pi epsilon_(0)) times
Two point charges 2q and 8q are placed at a distance r apart. Where should a third charge -q be placed between them so that the electrical potential energy of the system is a minimum
Three point charges +q, +2q and Q are placed at the three vertices of an equilateral triangle. Find the value of charge Q (in terms of q), so that electric potential energy of the system is zero.
Three point charge Q,4Q and 16Q are placed on a straight line 9 cm long.Charges are placed in such a way that the system has minimum potential energy .Then
Four point charges -Q, -q, 2q and 2Q are placed, one at each corner of the square. The relation between Q and q for which the potential at the centre of the square is zero is
