If light passes near a massive object, the gravitational interaction causes a bending of the ray. This can be thought of as happening due to a change in the effective refractive index of the medium given by n( r) = 1+ 2 GM//rc^2 where r is the distance of the point 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 from the original path as it grazes the object.

The dimensions of length are expressed as G^(x)c^(y)h^(z) , where G, c and h are the universal gravitational constant, speed of light and Planck's constant respectively, then :
