HCV fluid mechanics..

None

cylindrical body of outer diameter 20cm and mass 2kg floats in water with axis vertical. if it is slightly depressed and released find the time period of the resulting SHM???

net unbalanced force cause shm x be displacement therfore

ma=pi(r)²x(ro)g (ro)=density of water

as t=(2pi)root(x/a) therefore (2pi)root(x*2*10³/pir²(ro)gx (ro)=density of water

therefore (2pi)root2*10³/pi*10²*1*10

therefore 2(pi)root2/pi*10

therefore .5sec

isnt the above ans give by nik wrong since at one place he is using kg/m3 for density and on the other hand he has put r=10 instead of 0.1 in all equations
