Question:

A vector field \(\vec p\) and a scalar field \(r\) are given by
\(\vec p=(2x^2-3xy+z^2)\hat i+(2y^2−3yz+x^2)\hat j+(2z^2−3xz+x^2)\hat k\)
\(r=6x^2+4y^2 - z^2-9xyz - 2xy + 3xz-yz\)
Consider the statements P and Q.
P: Curl of the gradient of the scalar field r is a null vector.
Q: Divergence of curl of the vector field p is zero.
