1. The gravitational force due to the Sun on the planets in our solar system decreases as the planetary distance from the Sun increases. In your notebook, draw a larger version of Figure 3, and complete it for the force of gravity on an imaginary Earth-mass planet if its distance were between the Sun's radius, rs, and 100rs.
