Question

The centers of a 15 kg lead ball and a 130 g lead ball are separated by 6.0 cm.

What gravitational force does each exert on the other? Answer inNewtons.

What is the ratio of this gravitational force to the weight of the130 g ball?

Answer 1

F = G m_{1} m_{2} / d^2

G = 6.67*10^-11 Nm^2/kg^2

m_1 = 15kg

m_2 = 130g = .13kg

d = 6cm = 0.06m

F = 6.67*
`10^(-11)` * ((15*.13)/.06)

F = 2.16775e
`10^(-11)`

Explanation:

Answer 2

F = G
`m_(1) m_(2)` / d^2
G = 6.67*10^-11 Nm^2/kg^2 m_1 = 15kg m_2 = 130g = .13kg d = 6cm = 0.06m

F = 6.67*10^-11 * ((15*.13)/.06)
F = 2.16775
`*10^(-11)`
