I'm not really sure what I'm being asked to do with the following questions. Will someone help me?(adsbygoogle = window.adsbygoogle || []).push({});

How can you show that E(r)=-gradV(r) has zero curl an is irrotational, i.e. the quantity (grad x E) =0

How can you show that the magnetic field ,B(r)=grad x A(r), is divergenceless i.e. that the quantity grad dot B(r) =0?
