Question

The above diagrams show the electric field lines of charged particles.
Identify which of the following drawing represents two unlike point charges?

• A. Drawing I
• B. Drawing II
• C. Drawing III
• D. Drawing IV
• E. Drawing V

Answer 1

Answer: (E)

Drawing V

The electric field lines comes out from a positive charge and goes into a negative charge .

fig. (1) shows closed field lines , which is impossible.

fig. (2) shows two positive charges , because field lines are coming out from both the charges and showing repulsion.

fig.(3) shows a single positive charge.

fig.(4) shows a uniform electric field from a positive plate to a negative plate.

fig.(5) shows a positive and negative charge (two unlike charges) , because field lines are coming out from a charge ( positive) and going into another charge (negative).
