Question

How a blackhole 's gravity is powerful ?
​

Answer 1

Answer:

Because Black hole is dense due to which a large amount of mass fits in small space due to which black hole has large mass and small radius.

Escape velocity=√GM/√R

M large R small

Escape velocity increases

Answer 2

Not even light escapes.

The speed of light is 3×(10*8) m/s which is approx 5000 km/hr. The blackholes pull is stronger that particles this fast can not even escape.
