Q. A cyclist turns around a curve at 15 miles/hour. If the turns at double the speed, the tendency to overturn is
A) Doubled
B) Quadrupled
C) Halved
D) Unchanged
Explanation
(b) $F = \frac{mv^{2}}{r} \Rightarrow F \propto v^{2}$. If $v$ becomes double then $F$ (tendency to overturn) will become four times
