Detailed Solution
Download Solution PDFThe correct answer is 3 C.
- Electric potential difference is known as voltage, which is equal to the work done per unit charge to move the charge between two points against a static electric field.
- Therefore, \(Voltage = {Work Done \over Charge}\)
- Here, Given Voltage = 20 V and Work done = 60 J
Then electric charge = \({Work Done \over Voltage}\) = \({60 \over 20}\) = 3 C.
