A sphere is just immersed in a liquid. Find the ratio of hydrostatic force acting on top and bottom half of the sphere.

The volume of a hemisphere is four times that of a sphere. Find the ratio of the radius of the hemisphere to that of the sphere.

A cylinder of radius R, height H and density simga has a hemispherical cut at its bottom. The top of the cyliner is kept at depth h from the liquid surface. If the density of liquid is rho , find the hydrostatic force acting on the hemispherical surface of the cylinder.

Force On Surface Immersed In A Liquid

In a sphere is inscribed in a cube, find the ratio of the volume of cube to the volume of the sphere.

If the radius of a sphere is equal to the diameter of a hemisphere. Find the ratio of volume of sphere to that of the hemisphere.

An object is immersed in different liquids. Does same buoyant force acts on the object due to all the liquids?

A disc and a solid sphere of same mass and radius roll down an inclined plane. The ratio of thhe friction force acting on the disc and sphere is

The diagram shows the arrangement of three small uniformally charged spheres, A,B and C . The arrow indicate the direction of the electrostatic forces acting between the spheres (for example, the left arrow on sphere A indicates the electronstatic force on sphere A due to sphere B ). At least two of the spheres are positively charged. Which sphere, if any, could be negatively charged?
