A ball moves over a fixed track as shown in the figure. From A to B the ball rolls without slipping. Surface BC is frictionless. KA, KB and KC are kinetic energies of the ball at A, B and C, respectively. Then


[JEE' 2006]


             

  • a)
    hA > hC ; KB > KC

  • b)
    hA > hC ; KC > KA

  • c)
    hA = hC ; KB = KC

  • d)
    hA < hC; KB > KC

Correct answer is option 'A,B,D'. Can you explain this answer?

Using conservation of energy, we can write the following:

EA ​= mghA​ + K​A(1)

EB​ = KB​(2)

EC ​= mghC ​+ KC​(3)



Since EA ​= EB ​= EC​, we have the following:

KB​ > KA​

KB ​> KC​

From Eqs. (1) and (3), we get

EA ​− EC​ = 0

That is,

mg (hA​ − hC​) + [KA​ − KC​] = 0



From kinetic energy KB​, only translational part gets converted into potential energy at point C, we get hC ​< hA​. Therefore, KC ​> KA​
