A unit positive charge + qo placed anywhere in the vicinity of a positive point charge, experience a repulsive force directed
Correct answer: B. Radially outward
- A. Radially inward
- B. Radially outward
- C. Radially zero
- D. None of these
Explanation
A unit positive charge +qo placed in the vicinity of another positive point charge will experience a repulsive force directed radially outward. This repulsion occurs because like charges repel each other. The strongest force occurs when the charges are very close, decreasing as the distance increases. Thus, option B is correct.Option A is incorrect because a radially inward force would imply attraction, which is not the case for like charges. Option C is incorrect as the force is never zero unless the charges are infinitely distant. Option D is incorrect because option B correctly describes the situation.

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.
