Question

A point charge is taken from a point A to a point B in an electric field. Does the work done by the electric field depend on the path of the charge?

One Line Answer

Solution

Electrostatic field is a conservative field. Therefore, work done by the electric field does not depend on the path followed by the charge. It only depends on the position of the charge, from which and to which the charge has been moved.

Consider a coin of Example 1.20. It is electrically neutral and contains equal amounts of positive and negative charge of magnitude 34.8 kC. Suppose that these equal charges were concentrated in two point charges seperated by (i) 1 cm `(∼ 1/2 xx "diagonal of the one paisa coin")`, (ii) 100 m (~ length of a long 6 building) and (iii) 106 m (radius of the earth).

Two fixed, identical conducting plates (α and β), each of surface area S are charged to –Q and q, respectively, where Q > q > 0. A third identical plate (γ), free to move is located on the other side of the plate with charge q at a distance d (Figure). The third plate is released and collides with the plate β. Assume the collision is elastic and the time of collision is sufficient to redistribute charge amongst β and γ.

  1. Find the electric field acting on the plate γ before collision.
  2. Find the charges on β and γ after the collision.
  3. Find the velocity of the plate γ after the collision and at a distance d from the plate β.
