Alight ray just grazes the surface of the earth (m = 6.0 × 10 24 kg, r = 6.4×10 6 m). through what angle α is the light ray bent by gravitational lensing? (ignore the refractive effects of the earth’s atmosphere.) repeat your calculation for a white dwarf (m = 2.0 × 10 30 kg, r = 1.5 × 10 7 m) and for a neutron star (m = 3
