Q
Q: If the electric potential at a point is 100 V, what is the work done in moving a charge of 2 C from infinity to that point?
Solution:
Work done W = q * V = 2 C * 100 V = 200 J.
Steps: 6
Show Steps
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: Note the electric potential at the point where the charge is being moved to, which is 100 volts (V).
Step 4: Use the formula for work done (W) in moving a charge in an electric field: W = q * V.
Step 5: Substitute the values into the formula: W = 2 C * 100 V.
Step 6: Calculate the work done: W = 200 joules (J).
