1.	The angle made by the string of a simple pendulum with the vertical depends on time as `theta=pi/90sin[(pis^-1)t]`. Find the length of the pendulum if `g=pi^2ms^-2`A. 1B. 2C. 3D. 4
Answer» Correct Answer - A Here `2pisqrt((m)/(k)) = (2pi)/(omega) = (2pi)/(pi) = 2pisqrt((l)/(g)) rArr (l)/(g) = (1)/(pi^(2))` But `g = pi^(2)` therefore `l = 1 m`
