Problem 3QQ

Choose the best answer to each of the following. Explain your reasoning with one or more complete sentence.

Which of these objects has the smallest radius?

(a) a 1.2M Sun white dwarf

(b) the event horizon of a 3.0M Sun black hole

(c) the event horizon of a 10M Sun black hole

Step-by-Step Solution:

Solution 3QQ:

Step 1 of 2:-

Here we have to explain , which of the given objects has the smallest radius.

The options given are, 1.2 solar mass white dwarf, the event horizon of a 3 solar mass black hole and the event horizon of 10 solar mass black hole.

The white dwarf stars are formed after the death of a star whose mass is not sufficient to become a black hole. So, just after the death the star becomes a white dwarf. The mass of it is comparable to sun, but the size is comparable to earth.

So, the radius is significant.
