How is same charge possible on both C3 and C4 and potential difference between B and A is different and P and A is different?
and how is VAB = 2v using this ?
Homework Statement
In the above circuit, find the potential difference across AB.

"C34 = 4μf
C2,34 = 12μf
CEQ = 4.8μf
q = CEQ x V
the q on 1 is 48μC, thus
V1 = q/c
V1 = 6v
VPQ = 10 - 6 = 4v
By Symmetry of 3 and 4 , VAB = 2v"

When I had a school tour to A water park, there I observed that when a heavy boy used to slide down a water slide(and stop at β), he used to go further than where the ligher boy used to stop after sliding(α).
But the friction will act more on Heavier then why is he going further?
