Forces acting on two balls in a jar [closed]

Consider the following situation:

Two balls are inside a jar with diameter $D$. The balls are uniform in mass and both have the same diameter $d$.

Express the forces that acts at the colored dots in the figure.

Could any body give me a hint? It seems to me that I can't express one force without using the other.

You know there is a force $mg$ acting downwards at the centre of each ball. You known the balls aren't rotating so the moments of the forces add up to zero, and the balls aren't accelerating so you know the forces on each ball must add up to $mg$ upwards. So you can down a series of simultaneous equations relating the forces. –  John Rennie Aug 29 '14 at 10:43
I solved the question. Thanks to both of you. –  Udi Behar Aug 29 '14 at 11:27
