A simple pendulum has time period (T_1). The point of suspension is now moved upward according to the relation y = K t^2, (K = 1 m//s^2) where (y) is the vertical displacement. The time period now becomes (T_2). The ratio of (T_1^2)/(T_2^2) is (g = 10 m//s^2) .

A simple pendulum has time period T_1 . The point of suspension is now moved upward according to the relation. y = kt^2 (k = 2 m/ s^2 ) where y is the vertical displacement. The time period now becomes T_2 then the ratio of T_1^2 / T_2^2 (g = 10 m/ s^2 )

A simple pendulu has a time period T_(1) . The point of suspension of the pendulum is moved upword according to the relation y= (3)/(2)t^(2) , Where y is the vertical displacement . If the new time period is T_(2) , The ratio of (T_(1)^(2))/(T_(2)^(2)) is ( g=10m//s^(2))

A simple pendulum has time period 2s . The point of suspension is now moved upward accoding to relation y = (6t - 3.75t^(2))m where t is in second and y is the vertical displacement in upward direction. The new time period of simple pendulum will be

A simple pendulum has a time period of 3 s. If the point of suspension of the pendulum starts moving vertically upwards with a velocity =v=kt where k=4.4 m//s^(2) , the new time period will be (Take g=10 m//s^(2))
