why unstable equilibrium has high potential energy ? Share with your friends Share 0 Shobhit Mittal answered this Dear Student,unstable eqb means dUdx=0,d2Udx2 should be -ve at the equlibrium position .because when displaced from eqb position it moves from the eqb position and gains the Kinetic energy.thats why the PE is amximum at unstable eqb .Regards 1 View Full Answer
