The electric potential V at any point O (x, y, z all in metres)
in space is given by V=4x2 volt. The electric field at the
point (1m, 0, 2m) in volt/metre is-

18 along negative X–axis
28 along positive X–axis
316 along negative X–axis
416 along positive Z–axis

If a unit positive charge is taken from one point to another
over an equipotential surface, then-

1Work is done on the charge
2Work is done by the charge
3Work done is constant
4No work is done
