Hi,
again very simple problem
Metal sphere of radius R1 is charged to 10V.
It is then connected to another sphere with R2 = 2*R1.
What is the final potential?
V = E * distance
so in the case of disconnected it is E*R1
when connected R's sum up so it would be E*(R1+R2)
and since I don't know E but R2=2*R1
it is E*3*R1 so my solution is:
V_connected = V * 3
Is that correct?
