The time period of simple pendulum in stationary lift is T. If lifts moves upward with an acceleration equal to g the new time period will be a) Tb) T/under root 2c) T/2d) T/4Ans with reason please..

Time period T = 2$\prod$(l/g)1/2
When pendulum is in lift Tehe upward acceleration effectively adds to the gravitational acceleration.
So New time period
T’ = 2$\prod$[l/(g+g)]1/2 = T/(2)1/2
Hope it clears.
