Consider a disc rotating in the horizontal plane with a constant angular speed `omega` about its centre O . The disc has a shaded region on one side of the diameter and an unshaded region on the other side as shown in the figure. When the disc is in the orientation as shown, two pebbles P and Q are simultaneously projected at an angle towards R. The velocity of projection is in the y-z plane and is same for both pebbles with respect to the disc. Assume that (i) they land back on the disc before the disc has completed `(1)/(8)` rotation, (ii) their range is less than half the disc radius, and (iii) w remains constant throughout. Then

Consider a disc rotating in the horizontal plane with a constant angular speed omega about its center O. The disc has a shaded region on one side of the diameter and an unshaded region on the other side as shown in figure. When the disc is in the orientation as shown, two pebbles P and Q are simultaneously projected at an angle towards R. The velocity of projection in the y-z plane and is same for both pebbles with respect to the disc. Assume that (i) they land back on the disc before the disc has completed 1//8 rotation, (ii) their range is less than half the disc radius, and (iii) omega remains constant throughout. Then

Two identical discs of same radius R are rotating about their axes in opposite directions with the same constant angular speed omega . The discs are in the same horizontal plane. At time t = 0 , the points P and Q are facing each other as shown in the figure. The relative speed between the two points P and Q is v_(r) . In one time period (T) of rotation of the discs , v_(r) as a function of time is best represented by

A disc rotating about its axis with angular speed omega_0 is placed lightly (without any translational push) on a perfectly frictionless table. The radius of the disc is R . What are on the disc shown . Will the disc roll in the direction indicated?

A circular disc is rotating in horizontal plane about vertical axis passing through its centre without friction with a person standing on the disc at its edge. If the person gently walks to centre of disc then its angular velocity
