• # question_answer A 500 kg car takes around turn of radius 50 m with a speed of 36 km/hr. The centripetel                 force acting on the car will be: A)  1200 N                                 B)  1000 N C)  750 N                    D)         250 N

Here: Mass of car m = 500 kg Radius r=50 m Speed of car $\upsilon$= 36 km/hr                               $=\frac{36\times 5}{18}=10\,m/s$ The centripetal force is given by$F=\frac{m{{\upsilon }^{2}}}{r}=\frac{500\times {{(10)}^{2}}}{50}=1000\,N$
