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 `=5.98xx10^(24)kg`) have to be compressed to be a black hole ?

A

`10^(-9)m`

B

`10^(-6)m`

C

`10^(-2)m`

D

100m

Text Solution

Verified by Experts

The correct Answer is:
C
`v_e=sqrt((2GM)/R)=C or, R=(2GM)/(C^2)`, where ,C=velocity or light
