Question

True or False (Answer in Blank) (c) _____Unlike charges attract and like charges repel. (d) _____ If there is no charge within a volume of space, the electric field at an imaginary surface bounding that volume is everywhere zero. (e) _____ In electrostatic equilibrium, the electric field inside a conductor is zero. (f) _____ The net amount of charge produced in any physical process is zero. (g) Compare the magnitudes of the total electric field flux through the three closed surfaces below. No math required!

Explanation / Answer

c) True

(d) False

Reason:The flux through the surface must be zero, but the field itself need not be.

(e) True

(f) True

Reason:By law of conservation of charge

(g) By gauss law

elecric flux=q/epsilon0

since q is same for all ,so flux will also be same

so

(i)=(ii)=(iii)
