If two like charges of magnitude 1 x 10^-9 Coulomb and 9 x 10^-9 Coulomb are separated by a distance of 1 meter, then the point on the line joining the charges, where the force experienced by a charge placed at that point is zero, is:
Correct answer: C. Both A and B
- A. 0.25 m from the charge of 1 x 10^-9 Coulomb
- B. 0.75 m from the charge of 9 x 10^-9 Coulomb
- C. Both A and B
- D. At all points on the line joining the charges
Explanation
The position where the force on charge π is zero is x=0.25 m from q1 and distance from q2 is 0.75m

About Electrostatics
Electrostatics describes forces between charges through Coulomb's law, electric fields and field intensity, then uses electric potential to measure energy per unit charge. Capacitors store charge and electrical energy, with capacitance depending on geometry and dielectric material, not simply on the amount of charge present.
