Question

A $500$ $kg$ car takes a round turn of radius $50$ $m$ with a velocity of $36$ $km/hr$. The centripetal force is

• A. $250$ $N$
• B. $750$ $N$
• C. $1000$ $N$
• D. $1200$ $N$

Answer 1

The correct option is C $1000$ $N$

$F_c=\frac{m{v}^2}{r}$

$v=36\times \frac{5}{18}=10$ $m/sec$

$\Rightarrow F_c=\frac{500\times {10}^2}{50}$

$\Rightarrow F_c=1000$ $N$
