    Find Potential Difference Across AB: Capacitance Problem Solved

    Homework Statement In the above circuit, find the potential difference across AB. 2. Solution Online "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" 3.My question...

    Question on Laws of Motion observed in Real Life

    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?
