When a positive charge is moved in an electrostatic field from a point at high potential to a low potential, its kinetic energya)Remains constantb)Decreasesc)Increasesd)Either increase or remain constantCorrect answer is option 'C'. Can you explain this answer?

Question

Answer

You can generalise it by assuming a positive charge moving away from another positive charge. now both of them are repelling each other with some force. so that positive charge will accelerate which results in the increase in K.E.

Answer

As the potential energy decreases kinetic energy increases due to conservation of energy

Answer

Increases

Answer

We can generalise it by assuming a positive charge moving away from another positive charge. now both of them are repelling each other with some force. so that positive charge will accelerate which results in the increase in K.E.

Answer

Explanation:

When a positive charge is moved in an electrostatic field from a point at high potential to a point at low potential, its kinetic energy increases. This can be explained by the conservation of energy principle, which states that energy can neither be created nor destroyed, but it can be converted from one form to another.

Electrostatic Potential Energy:
The potential energy of a charge in an electrostatic field is given by the formula:

PE = qV

where PE is the potential energy, q is the charge, and V is the potential.

Conservation of Energy:
According to the conservation of energy principle, the total mechanical energy of a system remains constant if no external forces are acting on it. In this case, as the charge is moving in an electrostatic field, no external forces are acting on it.

Initially, when the charge is at a point of high potential, it has potential energy but no kinetic energy. As the charge moves towards a point of low potential, its potential energy decreases. According to the conservation of energy principle, this decrease in potential energy must be accompanied by an increase in kinetic energy. Therefore, the charge gains kinetic energy as it moves from a point at high potential to a point at low potential.

Conclusion:
In conclusion, when a positive charge is moved in an electrostatic field from a point at high potential to a point at low potential, its kinetic energy increases. This can be explained by the conservation of energy principle, which states that energy is conserved and can be converted from one form to another.
