Question

the electric potential v at any point (x y z) in space is given by v=4x^2 volt. calculate electric intensity at point (1m,0,2m).

Answer 1

differentiate this potential with respect to the x and then this will be electric field intensity.
now put the values of variable in that E vector.

Answer 2

Answer:

8

Explanation:

dv/dx=8x and x=1m so e.f.i=dv/dx=8
