A circular loop of rope of length $L$ rotates with uniform angular velocity $ω$ about an axis through its centre on a horizontal smooth platform. The velocity of pulse (with respect to rope) produced due to slight radial displacement is given by

Question Image

If the motion of the pulse and rotation of the loop, both are in same direction then the velocity of the pulse w.r.t. to ground will be:

A circular loop of rope of length $L$ rotates with uniform angular velocity $ω$ about an axis through its centre on a horizontal smooth platform. The velocity of pulse (with respect to rope) produced due to slight radial displacement is given by

Question Image

If both are in opposite direction, then the velocity of the pulse w.r.t. to ground will be:
