  • Figure shows some equipotential lines distributed in space. A charged object is moved from point A to point B. a) the work is done in fig (ii) is the least b) the work is done in fig (i) is the greatest

The figure shows some equipotential lines distributed in space. A charged object is moved from point A to point B.

a) the work is done in fig (ii) is the least

b) the work is done in fig (i) is the greatest

c) the work done in Fig (iii) is greater than Fig (ii) but equal to that in Fig (i)

d) the work done is the same in fig (i), fig (ii), and fig (iii)

Answers (1)

The answer is the option (d)

Explanation:-

 

The work done in moving a charge between two points in an electric field depends on the potential difference between the points, not on the path taken. Since equipotential lines represent locations where the potential is the same, the potential difference between two points (A and B) remains the same, regardless of the shape or arrangement of the equipotential lines.

  • The work done depends solely on the potential difference and the charge q. If the potential difference between points A and B is the same in all three cases (fig (i), fig (ii), and fig (iii)), the work done will be the same.
