Three uniform spheres of masses m1 = 3.50 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.

Answer 1

Maybe you tries to copy and paste the figure but that does not work here.
You need the trig to get the vector components.
