JEE MainPhysicsWork Power and EnergyMCQ+4 / −1
A point particle of mass m,m,m, moves long the uniformly rough track PQRPQRPQR as shown in the figure. The coefficient of friction, between the particle and the rough track equals μ.\mu .μ. The particle is released, from rest from the point PPP and it comes to rest at point R.R.R. The energies, lost by the ball, over the parts, PQPQPQ and QRQRQR, of the track, are equal to each other , and no energy is lost when particle changes direction from PQPQPQ to QRQRQR. The value of the coefficient of friction μ\muμ and the distance x(=QR),x(=QR),x(=QR), are, respectively close to: JEE Main 2016 (Offline) Physics - Work Power & Energy Question 116 English
