Answer 2

Given:

There are three galaxies G, G2 and Gy. Observations in G show that G2

and G3 are moving in opposite directions each with a speed of $0.5c$

To Find:

What is the speed of G, observed in G2

Step-by-step explanation:

• Here concept of Relative velocity can be used .
• Speed of G2 as shown in G was $0.5c$ in a direction.
• Speed of G as observed on G2 will be same but in opposite direction .

So the answer is 0.5c
