Question

In a bicycle the radius of rear wheel is twice the radius of front wheel. If rf and r, are the radius, and u, are speeds of top most points of wheel

Answer 1

Answer:

vF = vr

Step-by-Step Explanation:

Given : rr = 2 × rF

Vr & VF are speed at topmost point wheels.

Their angular speeds are different but linear speed will remain same

vr = vF  

#Correction in question : If rF and rr are the radius, vF and vr are speed of  top most points of wheel .

Answer 2

Answer: Vf=Vr

Explanation:

Speed of centres of both the wheels is same as that of cycle. We know that speed of top point is double that of centre. So speed of top points of both the wheels should be same. Hence vF=vr.
