A simple pendulum with a metallic bob has a time period T.The bob is now immersed in a non-viscous liquid and oscillated . If the density of the liuid is (1)/(4) that of metal , what will be the time period of the same pendulum? Hint : If the solid bob of the pendulum has relative densty D and has been submerged in a non-viscous liquid of relative density rho then effective acceleration due to gravity g' = g-(g)/(n) where n = (D)/( rho)
