Calculate the force of gravity between Earth and the Sun (the Sun's mass = 2.0×10^30 kg; average Earth-Sun distance = 1.5×10^11 m).

Use the same formula that I used in answering your last question, but with the masses of the earth and sun, and the earth-sun distance.

Use scientific notation. It's a big number. The baby-Mars attraction number would be very small.
