A star 2.5 times the mass of the Sun and collapsed to a size of 12 km rotates with a speed of 1.5 rev/s. Then an object placed on its equator (Mass of the Sun = 2\(x\)1030 kg).
- remain stuck to its surface due to gravity
- will fly off due to centrifugal force
- Initially will fly off and after some time return back to the surface
- none of these
Answer
