Question

Statement 1: A black hole is a starting stage of the formation of stars.
Statement 2: Light can escape from a black hole.

• A. Only statement 1 is correct
• B. Only statement 2 is correct
• C. Both statements are correct
• D. Both statements are incorrect

Answer 1

The correct option is D Both statements are incorrect

A black hole is an end-stage of stars having an initial mass larger than 25 times the mass of the Sun.

• After the supernova explosion, no pressure is capable of balancing their huge gravitational force and they continue contracting until everything collapses in a single point.
• As their size becomes smaller, their density and gravitational force increase tremendously. All nearby objects get attracted towards these stars and nothing can escape them, not even light.

Hence, both the statements are incorrect.
