(a) Mention the differences between electric field and magnetic field. Two charges of Q1=5nC and Q2=12nC have a distance of 7μm in vacuum. Find the force exerted on Q2 by Q1.

(b) State and explain Gauss's law. Write the Maxwell's equations in differential and integral forms for (i) Static EM fields, (ii) Time-varying EM fields.
