plz help
given insulator ball with radius R that charged with uniformed density p<0.
the ball is charged with -3Q
3 colon charges with Q>0 each one, are found inside the ball (look at the draw)
the charges found at triangle that it's sides are equal (each side length = d)
and d<=2R
the triangle found at a plane that divide the ball to two equal areas.
given that all the system is balanced, found the length d between the charges

thanks!
