Yes
A body gets stuck to the surface of a star if the inward gravitational force is greater than the outward centrifugal force caused by the rotation of the star.
Gravitational force, fg
Where,
M = Mass of the star = 2.5 × 2 × 1030 = 5 × 1030 kg
m = Mass of the body
R = Radius of the star = 12 km = 1.2 ×104 m
Centrifugal force, fc= mrω2
ω = Angular speed = 2πν
ν = Angular frequency = 1.2 rev s–1
fc = mR (2πν)2
= m × (1.2 ×104) × 4 × (3.14)2 × (1.2)2 = 1.7 ×105mN
Since fg > fc, the body will remain stuck to the surface of the star.
