1.	A lift is ascending with acceleration (g)/(3). Find the time period of simple pendulum of length L kept in lift.
Answer» `2PI sqrt((3L)/(g))` `pi sqrt((3L)/(g))` `2pi sqrt((3L)/(2g))` `2pi sqrt((2L)/(3g))` Solution :`implies g_(eff)= g-(g)/(3)= (2g)/(3)` `therefore T= 2pi sqrt((L)/(g_(eff)))= 2pi sqrt((L)/(2g"/"3))` `=2pi sqrt((3L)/(2g))`.
