Question:
How is ' work ' done in moving a charged particle? Work is the product of force and distance covered in the direction of force, there is distance but no force.
What point is infinity?
Answer:
Moving a charged particle involves putting force to move in against the forces of attraction and repulsion. So moving a charge involves application of force and some distance is also covered.
Infinity is a point where no forces of attraction or repulsion will exist on a charged particlem that is, it is very far from the point of origin.
