Question

C. When the center of Earth is 2 x 10^11meters from the center of Mars, the force of gravity

between the two planets is about 64.32 x 10^14 newtons. The mass of Earth is about
6 x 10^24 kilograms, and the mass of Mars is about 6.4 x 10^23 kilograms. Using these
values, estimate the gravitational constant.

Answer 1

When the center of Earth is 2 × 1011 meters from the center of Mars, the force of gravity between the two planets is about 64.32 × 1014 newtons. The mass of Earth is about 6 × 1024 kilograms, and the mass of Mars is about 6.4 × 1023 kilograms. Using these values, estimate the gravitational constant.
