Find the curl of the vector A = yz i + 4xy j + y k(a) xi + j + (4y – z)k(b) xi + yj + (z – 4y)k(c) i + j + (4y – z)k(d) i + yj + (4y – z)kThis question was addressed to me in quiz.Enquiry is from Vector Calculus topic in portion Vector Calculus of Electromagnetic Theory

Answer»

The correct option is (d) i + yj + (4Y – z)K

Explanation: CURL A = i(Dy(y) – DZ(0)) – j (Dx(0) – Dz(yz)) + k(Dx(4xy) – Dy(yz)) =

i + y j + (4y – z)k.
