Kinematics Question 700
Question: A cyclist turns around a curve at 15 miles/hour. If he turns at double the speed, the tendency to overturn it’s [CPMT 1974; AFMC 2003]
Options:
A) Doubled
B)Quadrupled
C) Halved
D)Unchanged
Show Answer
Answer:
Correct Answer: B
Solution:
$ F=\frac{mv^{2}}{r} $
therefore $ F\propto v^{2} $ .
If v becomes double then F (tendency to overturn) will become four times.
