A simple pendulum is kept in a lift. When the lift is moving upward its acceleration is 6 m/sec2 and when it is moving downward its acceleration is 1 m/sec2. Find the ratio of the time period of the simple pendulum when the lift is moving upward to the downward motion of the lift. (Take g = 10 m/sec2)
