Question

A star's mass is $60\times {10}^{30}\text{kg}$. Which of the following could be its final stage of life?

• A. Black hole
• B. White dwarf
• C. Nebula
• D. Neutron star

Answer 1

The correct option is A Black hole

Given:
The star's mass, $\text{M}=60\times {10}^{30}\text{kg}$
The mass of the Sun, ${\text{M}}_{\text{Sun}}=2\times {10}^{30}\text{kg}$

$⟹\text{M}=\frac{60\times {10}^{30}}{2\times {10}^{30}}{\text{M}}_{Sun}=30{\text{M}}_{\text{Sun}}$

We know that stars of mass greater than $25{\text{M}}_{\text{Sun}}$, would become super red giant stars in their last parts of life, and finally become a black hole.

Therefore, the given star becomes a black hole in the final stage of its life.
