Question

A 500 kg car takes a round turn of radius 50m with a speed of 36 km/hr. The centripetal force acting on the car will be

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

Answer 1

The correct option is B

1000N

$m=500kg,r=50mv=36\text{kmph}=36\times \frac{5}{18}=10m{s}_{-}1F=\frac{m{v}^2}{r}=\frac{500\times 10\times 10}{50}=1000N$
