Q. Consider the four field patterns shown. Assuming there are no charges in the regions shown, which of the patterns represents a possible electrostatic field?

 2279  178 Electric Charges and Fields Report Error

Solution:

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 because electrostatic field lines do not close on themselves.
