Abstract

Mahto et al. have derived the formula for the variation of the gravitational constant given by G^'=G/√(1-v^2/c^2 ) in very strong gravitational field of the compact bodies like super massive black holes and neutron stars (2013). In this paper, we have extended this work to show that the variation of gravitational constant in the strong gravitational field with respect to the spinning velocity of super dense stars is directly proportional to its spinning velocity.
