Question:
A charge Q₁ exerts some force on a second charge Q₂. If a third charge Q₃ is brought near, then the force exerted on Q₂ will:
A charge Q₁ exerts some force on a second charge Q₂. If a third charge Q₃ is brought near, then the force exerted on Q₂ will:
Show Hint
Electric force between two charges is independent of other charges.

- increase
- decrease
- remain unchanged
- increase if Q₃ has same sign as Q₁
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding Coulomb’s law. Force between two charges depends only on those two charges.
Step 2: Effect of third charge. The presence of Q₃ does not alter the force exerted by Q₁ on Q₂.
