What is the total amount of work to rotate a charge in the static electric field over a circular path? The potential at any point is given by `V=5x+3y+sqrt15z`.

What will be the amount of work done to rotate an electric dipole of moment 2.0 xx 10^(-20)C cdot m through an angle of 180^(@) in an electric field of intensity 1.2 xx 10^(4) V cdot m^(-1) ?

Two charges 5times10^(-8)c and -3times10^(-8)C are located 16cm apart-At what point(s) on the line joining the two charges is the electric potential zero? "Take the potential at infinity to be zero.

The electric potential at a point (x,y,z) is given by V=-x^2y-xz^3+4 . Find the intensity of electic field vecE at that point.

Find out the maximum charge on an unearthed hollow metal sphere of radius 3.0m for which it would not discharge into air. What would be the potential of the sphere in that condition? Assume that, electric discharge into air initiates at a field intensity of 3xx10^(6)V cdot m^(-1) .
