Sample questions
-
1.Assertion (A): The electric field points in the direction in which the potential decreases most rapidly. Reason (R): The relation between field and potential is E = -dV/dl.
- A.Both A and R are true and R is the correct explanation of A
- B.Both A and R are true but R is NOT the correct explanation of A
- C.A is true but R is false
- D.A is false but R is true
-
