Forces & Fields

Calculate the acceleration of the earth in its orbit around the sun and the net force exerted on the Earth.what exerts this force on the earth? Assume that the Earth's Orbit is a circle of radius 1.49*10^11m.

2. Relevant equations

g=GMm/r2

1 year=3.16*10^7

mass of the earth = 5.98*10^24kg

radius of the earth = 6.37*10^6m.

3. The attempt at a solution

I was approaching the question by using the equ. v2(v squared)/r.

but velocity is unknown and the distance between the sun and the earth.
