A liquid of mss m is set into oscillations in a U-tube of cross section A. Its time period recorded is T, where `T=2pisqrt(l//2g)` , here l is the length of liquid column. If the liquid of same mass is set into oscillations in U-tube of cross-section A/16 then determine time period of oscillation.

Mass is constant `rArr` volume x density `=` constant `rArr V_(1)d = V_(2)d` `(Al)d = [A/(16)l']d rArr l' = 16l :' T = 2pisqrt((l)/(2g)) :. (T')/(T) = sqrt((16l)/(l)) = 4 rArr T' = 4T`
