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 small hollow sphere having a small hole in it is immersed in water to a depth of 50cm, before any water penetrates into it. Calculate the radius of the hole, if the surface tension of water is 7.2 xx 10^(-2) Nm^(-1) .

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

A hollow shpere has a smalll hole. When the sphere is taken to a depth of 0.5 m inside water the air bubble start coming out from the hole. If the surface tension of water is 70xx10^-3 N//m , the radius of the hole is

A small hole is made at the bottom of a hollow sphere. The water enters into it when it is taken to a depth of 40 cm under water. If the surface tension of water is 0.07N m^(-1) , diameter 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-
