A) 250 N
B) 750 N
C) 1000 N
D) 1200 N
Correct Answer: C
Solution :
The centripetal force required for a car (mass m) to take a sharp turn of radius r with velocity v is \[F=\frac{m{{v}^{2}}}{r}\] Given, m = 500 kg, v = 36 km/h = \[36\times \frac{5}{18}=10\,m/s\,,\,r=50\,m\] Hence, \[F=\frac{500\times {{(10)}^{2}}}{50}=1000\,N\]You need to login to perform this action.
