Question

Find the variation of electric field on the line joining the two charge –

• A.
• B.
• C.
• D.

Answer 1

Answer: (C)

Answer 2

Since 2Q is the bigger charge hence electric field will be zero near the smaller charge. Hence graph (1) and (2) are wrong. On both the charges the electric field will be infinite. Hence (4) is wrong and correct answer is (3).
