Q1:

For static electric and magnetic fields in an homogenous source-free medium, which of the following represents the correct form of Maxwell's equations?

A Δ.E = 0
Δ x B = 0

B Δ.E = 0
Δ.B = 0

C Δ x E = 0
Δ x B = 0

D Δ x E = 0
Δ.B = 0

ANS:D - Δ x E = 0
Δ.B = 0

Curl of electric field is zero. Divergence of magnetic field is zero.
