Question

shows that the electric field at any point is equal to negative potential gradient at the point. - ​

Answer 1

Answer:

i dont know ask anyone or ur brothers and sisters

Explanation:

Answer 2

Explanation:

As we know, the potential at any point due to a point charge q is given by V=kq/r , where k is known as the constant of proportionality whose value is 9 x 10^9 Nm^2/C^2 and r is the distance between the point and the charge q.

Now taking del operator on both sides of the equation V=kq/r
