A liquid is kept in a cylindrical vessel. When the vessel is rotated about its axis, the liquid rises at its sides. If the radius of the vessel is 0.05 m and the speed of rotation is 2 revolutions per second, the difference in the heights (in cm ) of the liquid at the centre and at the sides of the vessel is (take g =10 ~ms ⁻² and ^2=10 )

Correct answer

2

Step-by-step solution

Using Bernoulli's theorem 1 2 v^2=p= g h or h= v^2 2 g h .......(i) Put: V=r =r(2 v) in (1)
