Q. 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
A) $R_{1} = R_{2}$
B) $R_{1} < R_{2}$
C) $R_{1} > R_{2}$
D) $R_{1} \geq R_{2}$
Explanation
(b) Reaction on inner wheel $R_{1} = \frac{1}{2}M\left\lbrack \begin{array}{r}
g - \frac{v^{2}h}{ra} \\
\
\end{array} \right\rbrack$
Reaction on outer wheel $R_{2} = M\left\lbrack \begin{array}{r}
g + \frac{v^{2}h}{ra} \\
\
\end{array} \right\rbrack$
where, $r = \ $radius of circular path,$\ 2a =$distance between two wheels and $h = \ $height of centre of gravity of car
