Question

If f and g are irrotational , prove that fxg is solenodal

Answer 1

Can I ask a question?

Answer 2

Yes you can, @sauravshakya.

Answer 3

any solution for my problem ????

Answer 4

so we have \[\nabla \times f=0\]\[\nabla \times g=0\]and u want to prove\[\nabla.(f\times g)=0\]right?

Answer 5

u just need to remember this identity\[\nabla.(f\times g)=(\nabla \times f).g-f.(\nabla \times g)\]

Answer 6

is this the complete solution with all the steps ????

Answer 7

let me ask a question first

what is a irrotational field?

Answer 8

what is a Solenoidal vector field ?
