RAJASTHAN PMT Rajasthan - PMT Solved Paper-2005

  • 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

    Correct Answer: B

    Solution :

    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\[F=\frac{m{{\upsilon }^{2}}}{r}=\frac{500\times {{(10)}^{2}}}{50}=1000\,N\]
