The electric potential V at any point x,...

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

Text Solution

Verified by Experts

Here, `V = 4 x^(2), E = ?, x = 1m , y = 0, z = 2m`
`E = (del V)/(del x) = - (del)/(del x) (4x^(2)) = -8x = 2(1) = -8 V m^(-1)` along negative direction of x-axis.
