G (m )(4-m) /.25^2 = 2.5*10^-10
(4 m-m^2)=2.5*10^-10*.0625*10^11 /6.67
4 m - m^2 = .0234 * 10^1 = .234
m^2 - 4 m + .234 = 0
m = [ 4 +/- sqrt(16 - .0937) ]/2
= 2 +/- 1.997
so I suspect one of them is tiny and the other is about 4
.00293 and 3.997
two objects attract each other gravitationally with a force of (2.5)(10^-10)N when they are 0.25m apart. Their total mass is 4.0 kg. Find their individual masses.
