Kinematics Question 722
Question: A car is moving on a circular path and takes a turn. If $ R _{1} $ and $ R _{2} $ be the reactions on the inner and outer wheels respectively, then [MH CET (Med.) 2001]
Options:
A) $ R _{1}=R _{2} $
B) $ R _{1}<R _{2} $
C) $ R _{1}>R _{2} $
D)$ R _{1}\ge R _{2} $
Show Answer
Answer:
Correct Answer: B
Solution:
Reaction on inner wheel $ R _{1}=\frac{1}{2}M[ g-\frac{v^{2}h}{ra} ] $
Reaction on outer wheel $ R _{2}=\frac{1}{2}M[ g+\frac{v^{2}h}{ra} ] $
where, r = radius of circular path,
2a = distance between two wheels
and h = height of centre of gravity of car.
