Question

The relation between vector potential and field strength is
given by
a) Gradient
b) Divergence
c) Curl
d) Del operator​

Answer 1

The correct answer is option (a) Gradient.

Explanation:

• The relation between vector potential and field strength is given by Gradient.
• The vector potential and field is given by, E = -Del (V).
• The Laplacian operator is the divergence of gradient of a vector, which is also called del2V operator.
• In vector calculus, the gradient of a scalar-valued differentiable function f of several variables is the vector field \nabla f whose value at a point p is the vector whose components are the partial derivatives of f at p.
