# Given below are two statements:  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 bob is charged and kept in a horizontal electric field, then the time period will be decreased.   1. Both (A) and (R) are True and (R) is the correct explanation of (A). 2. Both (A) and (R) are True but (R) is not the correct explanation of (A). 3. (A) is True but (R) is False. 4. (A) is False but (R) is True.
