A simple pendulum is suspended in a lift which is going up with an acceleration of 5 m/s2. An electric field of magnitude 5 N/C and directed vertically upward is also present in the lift. The charge of the bob is 1 μC and mass is 1 mg. Taking g=π2 and length of the simple pendulum I m, the time period of the simple pendulum (in sec) is ____.
