Question

The table shows the mass of four planets.

Planet Mass (1024kg)
Venus 4.87
Earth 5.97
Jupiter 1898.00
Neptune 102.00

Which shows the correct order of the planets when listed from the greatest gravitational pull to the least?
A.
Earth → Venus → Neptune → Jupiter

B.
Jupiter → Earth → Venus → Neptune

C.
Jupiter → Neptune → Earth → Venus

D.
Neptune → Venus → Earth → Jupiter

Answer 1

C

Gravitational acceleration at a planet's surface is g = GM/R^2. Using known values, the surface gravities are approximately:
- Jupiter ≈ 24.8 m/s^2
- Neptune ≈ 11.2 m/s^2
- Earth ≈ 9.8 m/s^2
- Venus ≈ 8.9 m/s^2

So the order from greatest to least is Jupiter → Neptune → Earth → Venus.
