I need a solution to this. If it is possible to show me the complete solution
See attach JPG
Use geometry, and show what you have done so far.
I`ve got Ground and A and Ground and B. Is there a way of determining the angle (not from the answers) where circel A and C make contact, using the radius?
1. The forces between the balls acts along the contact normals.
2. If you extend the line of the normal on the surface into the sphere's you'll end up in that sphere's center.
3. But that means you can determine the angles from the triangle drawn between the 3 centres:
Let R be the radius in the big sphere, r the radius in the two smaller spheres:
Then the triangle has sides: 2r,r+R,r+R
thank you sorted
