Questions
Concrete blocks of masses and are balanced on two identical vertical springs. . The gravitational potential energy of each system is zero at the equilibrium position of the springs. Which statement is true for the total mechanical energy of the systems when the blocks are balanced on the springs?
detailed solution
Correct option is C
KxA = mAgKxB = mBg ⇒ xAxB = mAmB =2 ⇒ xA = 2xBPEA = 12Kx2APEB = 12KxB2 ⇒PEAPEB = (xAxB)2 = 4So for A, potential energy of spring is four times that for B.So EA = 4EBTalk to our academic expert!
