Divergence of gradient of a vector function is equivalent to

Electronics and Communication Engineering (ECE) : Electromagnetic Field Theory - Quiz(MCQ)

Null vector

Curl operation

Laplacian operation

Double gradient operation

Correct Answer : Option (C) : Laplacian operation

Explanation : Div (Grad V) = (Del)²V, which is the Laplacian operation. A function is said to be harmonic in nature, when its Laplacian tends to zero.
