what will be work done in taking a point charge q from a point x to y on the circumferenceof the given circle
Answers
Explanation:
The points A and B will have the equal distance because every point in the circumference of a circle will have equal distances from the centre which is +q.
Due to the charge of the centre of the circle, every point at the circumference will be at equipotential.
As there is no transformation of potential energy in moving a charge in the equipotential path, there is no work done or say, the work done is zero.
Answer:
As we know for a point charge, the equipotential surfaces are concentric spheres with the centre located at the charge
so when a charge is moved in a circular orbit around the given charge , it is actually being moved along an equipotential surface and hence the net work done is zero as there is no change in the potential.
