CBSE Class 12 Physics 2023 Outside Delhi Set 1 Paper

Question : 17

Total: 35

Assertion (A): Work done in moving a charge around a closed path, in an electric field is always zero.
Reason (R): Electrostatic force is a conservative force.

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 and Reason (R) is NOT the correct explanation of Assertion (A).
Assertion (A) is true and Reason (R) is false.
Assertion (A) is false and Reason (R) is also false.

Solution: 👈: Video Solution

Electric field is said to be conservative since, work done in this field is path independent. It depends on the end points only. So, in an electric field, total work done in moving a charge from a point to the next point and again back to the first point is zero.
Hence, assertion and reason both are true and reason explains the assertion.
