A pan balance has a container of water with an overflow spout on the right-hand pan as shown. It is full of water right up to the overflow spout. A container on the left-hand pan is positioned to catch any water that overflows. The entire apparatus is adjusted so that it’s balanced. A brass weight on the end of a string is then lowered into the water, but not allowed to rest on the bottom of the container. What happens next?

Water overflows and the right side of the balance tips down

Water overflows and the left side of the balance tips down.

Water overflows but the balance remains balanced

Water overflows but which side of the balance tips down depends on whether the brass weight is partly or completely submerged

Solution

From the figure it is clear that the level of water in the right pan remains the same thus pressure $(\&force)$ at the bottom of right vessel is constant but that on the left pan increases thus overflows $\&$ the left side of the pan tips down

A solid sphere of radius $r$ made of a soft material of bulk modulus $K$ is surrounded by a liquid in a cylindrical container. A massless piston of area a floats on the surface of the liquid, covering entire cross-section of cylindrical container. When a mass m is placed on the surface of the piston to compress the liquid, the fractional decrement in the radius of the sphere$\left( {\frac{{dr}}{r}} \right)$ is
