A black hole is an object whose gravitational field is so strong that even light cannot escape from it. To what approximate radius would earth (mass = 5.98  x 1024 kg) have to be compressed to be a black hole

a
10-9 m
b
10-6 m
c
10-2 m
d
100 m

detailed solution

Correct option is C

Escape velocity v=2GMR=c= speed of light⇒R=2GMc2=2×6.6×10−11×5.98×10243×1082m= 10-2 m
