two spheres (Issac physics) statics level 6

What diagram have you drawn for the spheres and theta and ...?

just this

I got 16.1 for the question but it says it's incorrect.
The question is like this:
https://isaacphysics.org/questions/two_spheres?board=b212f0eb-bab0-477a-ad0f-dd5471f67b58&stage=a_level
two spheres with radii 8r and 4r, mass 4mg and mg and in contact with a force 2mg applying at the top of the big sphere. the system is in equilibrium. the first question asks the normal reaction on the ground to the big sphere. I resolved all the forces and got 16.1 for several times.... but it's wrong could anyone help with me pleasessss!
Thanks so much!

Bro How to proceed to Part B plss iam struggling a lot

If you have done Part A, you have 4 equations for 4 unknown forces. But you would have solved for N and F_r
For Part B, you need to know how is G and J related.
