A uniform disc of mass m and radius R is released gently on a horizontal rough surface such that centre of the disc has velocity `V_(0)` towards right and angular velocity `omega_(0)` (anticlockwise) as shown. Disc will certainly come back to its initial position if A. `omega_(0)R=2V_(0)`B. `omega_(0)Rlt2V_(0)`C. `omega_(0)Rgt2V_(0)`D. Data insufficient

Answer» Correct Answer - C
For maximum X-coordinate
`O=3V_(0)-2a_(1)t" "t=(3V_(0))/(2a_(1))`
