Assertion At a point in space, the electric field points towards north. In the region, surrounding this point the rate of change of potential will be zero along the east and west Reason Electric field due to a charge is in the space around the charge
- A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
- B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
- C. Assertion is correct but Reason is incorrect
- D. Assertion is incorrect but Reason is correct
Step-by-step solution
Assertion is correct because if the electric field points north, the potential gradient in the east-west direction (perpendicular to north) is zero. Reason is correct as electric fields exist around charges, but it does not specifically explain why the rate of change of potential is zero along east-west; it is a general statement, not a direct explanation.
