Question

Four masses are positioned at the corners of a rectangle, as indicated in the figure below (not to scale).

(a) Find the magnitude and direction of the net force acting on the 2.0 kg mass if x = 0.40 m and y = 0.12 m.

N (magnitude) ?

counterclockwise from the x-axis, which points to the right ?

Explanation / Answer

F=GmM/r2

by adding three forces due to rst three masses we can find F.

it is an attractive force, all the masses will pull that mass in its own direction. Net direction will be towards 4 kg weight.

If the distance become double, force will reduce four times
