Answer 2

Answer:

Escape velocity of that planet will be 2 times from the earth.

Explanation:

• If the mass of planet is eight times then escape velocity = 2 √2 times.
• Hence the net escape velocity will be increase. 2 √2 × (1/√2)= 2 times now.
• Now it is clear that the escape velocity of that planet will be 2 times from the earth.
