Question: If the electric potential at a point is 10 V, what is the work done in bringing a charge of 2 C from infinity to that point?

Options:

Correct Answer: 20 J

Solution:

Work done = Charge × Potential = 2 C × 10 V = 20 J.

If the electric potential at a point is 10 V, what is the work done in bringing a charge of 2 C from infinity to that point?

If the electric potential at a point is 10 V, what is the work done in bringing a charge of 2 C from infinity to that point?

Step 1: Understand that electric potential (V) is measured in volts (V) and represents the potential energy per unit charge.
Step 2: Identify the charge (Q) being moved, which is given as 2 coulombs (C).
Step 3: Recognize that the electric potential at the point is given as 10 volts (V).
Step 4: Use the formula for work done (W) in moving a charge in an electric field: W = Charge × Potential.
Step 5: Substitute the values into the formula: W = 2 C × 10 V.
Step 6: Calculate the work done: W = 20 joules (J).

Electric Potential and Work – The relationship between electric potential (voltage) and work done in moving a charge in an electric field.
