Question

Assertion (A): Potential difference is the amount of work done in moving a unit charge from one point to another point in an electric field.

Reason (R): The unit of electric potential or potential difference is volt.

Options

• Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion (A).

• Both Assertion (A) and Reason (R) are true but Reason (R) is not the correct explanation of Assertion (A).

• Assertion (A) is false, but Reason (R) is true.

• Assertion (A) is true, but Reason (R) is false.

Answer 1

Both Assertion (A) and Reason (R) are true but Reason (R) is not the correct explanation of Assertion (A).

Explanation:

Potential difference is defined as the work done in moving a unit charge from one point to another in an electric field, so the assertion is true. The volt is the SI unit of potential difference, so the reason is also true. However, the unit of a quantity does not explain its definition. Therefore, the reason is not the correct explanation of the assertion.
