NEET 2002 Physics question
A point P consider at contact point of a wheel on ground which rolls on ground without slipping then value of displacement of point P when wheel completes half of rotation (If radius of wheel is 1m) :
Answer: (2)
Solution
In pure rolling, in half a rotation the centre moves forward by half the circumference, . The point P, which was at the bottom (on the ground), is then at the top of the wheel, i.e. at height above the ground. The horizontal displacement of P is m and
