Two objects, one has a mass of 600 kg, have a gravitational force between them of 1.5 X 10^-5 N and they are a distance of 2 m apart, what is the mass of the other object?

Question

anonymous · Answer

I'm not sure how to set up the equation.

anonymous · Answer

the force of gravity between two masses is given by:
$$F=G{m_1m_2\over d^2}$$
F = force of gravity
G = universal gravitational const.
m1, m2 = the two masses
d = distance between their centers of masses

anonymous · Answer

I don't want to find the force of gravity F I want to find the mass of the other object

anonymous · Answer

i know, 
but you have to use that equation 
$F = 1.5\times10^{-5}$
$m_1=600$
$d=2$
G = look up at the back of the book or your formula sheet
plug em in, and solve for "m_2"

anonymous · Answer

no. do not complicate your math there. pretty straight forward
$$
1.5\times10^-5=6.67\times10^{-11}\times\frac{600m}{2^2}
$$
