Assertion (A): If the bob of a simple pendulum is kept in a horizontal electric field, its period of oscillation will remain the same.
Reason (R): If the bob is charged and kept in a horizontal electric field, then the time period will be decreased.
- Both A and R are true and R is the correct explanation of A.
- Both A and R are true but R is not the correct explanation of A.
- A is true but R is false.
- A is false but R is true.
Answer
(D) A is false but R is true.
