Demonstrate that Maxwell'sequations grad xx E = -del B //del t andgrad.B = 0 are compatible, i.e.,the firstone doesnot contradict the secound one.

Answer»

Solution :From`vec(grad) XX vec(E) = (del vec(B))/(del t)`
we get on takingdivergence
`0 = - (del)/(del t)` div `vec(B)`
This is COMPATIBLE with div `vec(B) = 0`
