Question

The electric potential V at any point (x, y, z).
(all in metres) in space is given by V = 4X² volts.
The electric field at the point (1, 0, 2) in volt/meter,
is :-
(1) 8 along negative X-axis
(2) 8 along positive X-axis
(3) 16 along negative X-axis mon
(4) 16 along positive X-axis​

Answer 1

here is your ans.

electric potential at any point xyz

given by :- v = 4x²

we know that :-

E = -dv/dx

so, E = -8x

so, electric field at (1,0,2)

E = -8

so, correct option is (2)

hope it helps.
