Question

Consider the four field patterns shown. Assuming there are no charge in the regions shown, which of the patterns represent a possible electrostatic field?
A.
B.
C.
D.

Answer 1

Correct Answer - b
Pattern (a) can be eliminated because field lines cannot simultaneously originate from and converge at a single point, (c ) can be eliminated because there are no charges in the region, and so there are no sources of field lines, (d) can be eliminated beacuse electrostatic fields lines do not close on themselves.
