Two spherical objects have masses of 400 kg and 50 kg. Their centers are separated by a distance of 15 m. Find the change in the gravitational attraction Force between them if the first mass changes to 800 kg and the other mass and distance do not change.

• It does not change.

• It increases by a factor of 2 times stronger

• It decreases by a factor of 1/2 as weak

• It increases by a factor of 1/2 times stronger

Two spherical objects have masses of 100 kg and 50 kg. Their centers are separated by a radius distance of 10 m. Find the change in the gravitational attraction Force between them if only the radius distance increases to 20 m in length.

• It does not change the overall force of gravitation.

• It increases by a factor of 2 times stronger

• It decreases by a factor of 1/4 as weak

• It increases by a factor of 4 times stronger

Two spherical objects have masses of 50 kg and 50 kg. Their centers are separated by a radius distance of 20 m. Find the change in the gravitational attraction Force between them if the radius distance doubles in length, and the one mass doubles while the other mass doesn't change.

• It does not change the overall force of gravitation.

• It increases by a factor of 2 times stronger

• It decreases by a factor of 1/4 as weak

• It increases by a factor of 4 times stronger

What is the overall effect on the force due to the changes?

• Force increases and is 2 times stronger .

• Force increases and is 4 times stronger now.

• Force decreases and is 2 times weaker now.

• The force does not change since the effects cancel out.

What is the Universal law of gravitation equation? (remember, d and R are the same thing)

• F = m₁⋅m₂/d²

• G = m₁⋅m₂/(d)²

• F= d²/m₁⋅m₂

• G= d²/m₁⋅m₂
