two 200 kg lead spheres are suspended from 200 m long massless cables.the tops of the cables have been carefully anchored exactly 1 m apart.what is the distance between the centers of two spheres?
i tried to use gravitional forces to calculate the distance,but here we have cables.
please help me get this question.
thanks

So you have the force of attraction on the left ball towards the right. It's in equilibrium, right? The cable develops an angle to vertical. The tension in the cable can be resolved into vertical (which has to be equal and opposite the weight) and horizontal (which has to be equal and opposite the attraction pulling it to the right). From this you can get the angle and the distance of displacement towards the other ball.
Same amount of displacement of the other to the left.
