PLEASE ANSWER BOTH QUESTIONS

1.The centers of a 15kg lead ball and a 50g lead ball are separated by 10cm

A) what gravitational force does each exert on the other (answer should be in Newtons and doesn't depend on x10)

B) What is the ratio of this gravitational force to the weight of the 50g ball

2. The radius of the Earths very nearly circular orbit around the sun is 1.5x10^11 m

A) find the magnitude of the earth velocity as it travels around the sun (assume a year of 365 days)

Ive already answered this problem = 30 km/s

B) Find the magnitude of the earths angular velocity as it travels around the sun (assume a year of 365 days and answer should be in s^-1)

C) Find the magnitude of the earths centripetal acceleration as it travels around the sun (assume a year of 365 days and the answer should be in m/s^2)

Explanation / Answer

1)

a) 5*(10^-9)...........
