2.A student is calculating the gravitational force between the Earth and the sun. She knows that mass of the Earth is 5.972 x 1024 kg, the mass of the sun is 1.989 x 1030 kg, and the distance between the Earth and the sun is 1.496 x 1012 meters. What piece of information is she missing to be able to find the gravitational force?(1 point)
the direction of the force between the Earth and the sun
the gravitational constant, G
how long it takes for the Earth to revolve around the sun
how much heavier the sun is compared to the Earth
