2-Three uniform spheres of masses m1 = 3.00 kg, m2 = 4.00 kg, and m3 = 5.50 kg are placed at the corners of a right triangle (see figure below). Calculate the resultant gravitational force on the object of mass m2, assuming the spheres are isolated from the rest of the Universe.

Calculate the resultant gravitational force on the object of mass m2, assuming the spheres are isolated from the rest of the Universe.

Explanation / Answer

the gravitational force is

F = (Gm^2/r^2)

where G = 6.67 x 10^-11 Nm^2/kg^2,m = 66.0 kg and r = 1.10 m

the net gravitational force on m2 is

F = (F12^2 + F32^2)^1/2
