Q1An object of mass m is located at radius r form centre of black hole with Schwarzschild radius Rc.Find attractive force exerted by black hole on body
Q2 Astronomers observed a small massive object at centre of our milky way galaxy.A ring of materials orbits this massiv object,the ring has a diameter of about 15 light years and an orbital speed of 200km/s.hat is mass of massive object at the centre of milky way galaxy ?
G=6.67 *10-11
1 light yr=9.5 * 1015 m
Q3 Many astronomers believe that object in middle of milky way galaxy(as in 2) i s a black hole.If this si the case,calculate Schwarzschild radius Rc of this black hole
29Ans 1 ..Since the radius of the Black Holes is generally very small..so we can consider the black hole as a point mass..then the force of attraction can be easily calculated....
I hope i am right
well for all those who are wondering wat Schwarzschild radius is?...actually it is the largest size of the body for which it could behave as a blackhole..and the formula is R ≤ 2GM / c2
106eure.. i was just gonna post this Para (Last yrs RTPF)
I got the first answer,.
(yeah govind right..consider black hole as point charge)
but couldnt get the next two.
