Question

Calculate the work done by the electrostatic field in moving a charge of 2 coulomb from one point to another, if the potential of the first point is 20V, and the second - (5V)

Answer 1

To calculate the work done by the electrostatic field in moving a charge from one point to another, you can use the formula:

work = charge * (final potential - initial potential)

In this case, the charge is 2 coulombs, the initial potential is 20V, and the final potential is -5V. Plugging these values into the formula, we get:

work = 2 coulombs * (20V - (-5V))

= 2 coulombs * (25V)

= 50 Joules

Therefore, the work done by the electrostatic field in moving the charge from one point to another is 50 Joules.
