Give the CGS unit of universal gravitational constant (G).

Define universal gravitational constant (G).

The value of Universal Gravitaitonal Constant is

If the value of universal gravitational constant is 6.67xx10^(11) Nm^2 kg^(-2), then find its value in CGS system.

The dimensions of universal gravitational constant are :-

Draw schematic drawing of Cavendish's experiment for determination of universal gravitational constant G and obtain formula used in it.

If light passes near a massive object, the gravitational interation causes a bending of the ray. This can be thought of as heappening due to a change in the effective refrative index of the medium given by n(r) =1 +2 GM//rc^2 where r is the distance of the point of consideration from the centre of the mass of the massive body, G is the universal gravitational constant, M the mass of the body and c the speed of light in vacuum. Considering a spherical object find the deviation of the ray form the original path as it graxes the object.

The value of universal gravitational constant G depends upon :
