Force between balls will be (c) zero
_______________________
Initially :
- 1st Charge (Q1) = +3μC
- 2nd Charge (Q2) = -3μC
- Force = F
Finally :
- 1st Charge (Q1') = +3μC + 3μC = 6μC
- 2nd Charge (Q2') = -3μC + 3μC = 0μC
- let distance between balls (d) = x
Use Coulomb's Law for Final charges :

Answer:
Given:
2 balls having +3 μC and -3 μC attract each other with force F. Now +3 μC charge is added to both the balls.
To find:
New force of attraction
Concept:
Electrostatic force depends on 2 aspects :
- Directly proportionally to product of charges.
- Inversely proportional to square of distance of separation.
Calculation:
k is also called Coulomb's constant. The value of this constant is 1/4πε .
Now , new charges will be :
New force be F2 :
So the new force will be 0 N .
Final answer :
