In a bicycle the radius of rear wheel is twice the radius of front wheel. If rF and rr are the radius, uF and ur are speeds of top most points of wheel, then:
A
ur= 2 uF
B
uF = 2 ur
C
uF = ur
D
uF > ur
Answer
uF = ur
Explanation
Solution
The velocity of the top point of the wheel is twice that of centre of mass and the speed of centre of mass is same for both the wheels (Angular speeds are different).
