Question

if a is constant function then div (a×b )=​

Answer 1

Step-by-step explanation:

How find the divergence and Curl of the following:

(a⃗ ⋅r⃗ )b⃗ ,

where a⃗ and b⃗ are the constant vectors and r⃗ is the radius vector.

I have tried solving this by supposing r⃗ =(x,y,z) and got answer as

div((a⃗ ⋅r⃗ )b⃗ ) = a⃗ ⋅b⃗

but I was wondering if anybody could help me to solve it by using the formulas involving Nabla Operator.

Thanks
