Question

Please answer the question and subquestions entirely. This is one single question. According to the official guideline, I can ask two subquestions! Thank you!

Two bodies, masses m ₁ and m ₂, attract each other with force F. If one of the masses is doubled, the new gravitational force will be:

		2 F
		F/2
		F/4
		4 F

The value of g at an altitude above Earth equal to one Earth diameter is:

		9.8 m/s²
		4.9 m/s²
		2.5 m/s²
		1.9 m/s²
		1.1 m/s²

The escape velocity at the surface of Earth is 11 km/s. What is the escape velocity at the surface of a planet whose radius is 4 times and whose mass is 100 times that of Earth?

		1.60 km/s
		8 km/s
		55 km/s
		200 km/s
		none of the above
