Then the work done by electric field on a 2 C charge if it is taken from (1,1,0) to (3,0,0) is :

An electric field ‘E’ whose direction is radially outward varies as distance from origin ‘r’ as shown in the graph E is taken as positive if its direction is away from the origin. Then the work done by electric field on a 2 C charge if it is taken from (1,1,0) to (3,0,0) is :

A charge -q and another chage +q are kept at two points A and B respec tively. keeping the charge +Q fixed at B the charge -q at A is moved to another point C such that ABC forms an equilateral triangle of side l. The net work done in moving the charge -q is
