A small hollow sphere which has a small hole in it is immersed in water to a depth of 40 cm, before any water is penetrated into it. If the surface tensionof water si `0.073 Nm^(-1)`, find the radius of the hole.

A small hollow sphere having a small hole in it is immeresed into water to a depth of 20 cm before any water penetrates into it. If the surface tension of water is 73 dyne cm^-1 , find the radius of the hole.

A hollow sphere which has a small hole in its bottom in water to a depth of 30 cm before any water enters in it. If the surface tension of water is 75 dynes/cm then find the radius of the hole in metres (taking g=10m//s^(2))

A hollow sphere has a small hole. When the sphere is taken to a depth of 0.5 m inside water the air bubbles started coming out from the hole. If the surface tension of water is the radius of the hole is

There is a small hole in a hollow sphere . The water enters in it when it is taken to depth of 40 cm under water. The surface tension of water is 0.07 N/m. The diameter of hole is-

Find the excess pressure inside a liquid drop of radius 2 cm, if the surface tension of water is 0.073 N m^(-1)

A hollow sphere has a small hole in it. On lowering the sphere in a tank of water, it is observed that water enters into the hollow sphere at a depth of 40 cm below the surface. Surface tension of water is 7 xx 10^(-2) N//m . The diameter of the hole is

A vessel has a small hole at its bottom. If water can be poured into it upto a height of 7 cm without leakage (g=10ms^(-2) ) the radius of the hole is (surface tension of water is 0.7Nm^(-1) )

A sphere of radius 5cm is immersed in water filled in a cylinder, the level of water rises 5/3c mdot Find the radius of the cylinder.
