A motor vehicle of mass 1000 ~kg is moving on a circular road having banking angle 30^ and coefficient of friction 0.2 . Then the normal reaction force on the motor vehicle is about (Acceleration due to gravity =10 ~ms ⁻² )

Options

  1. A6750 ~N
  2. B9060 ~N
  3. C1070 ~N
  4. D13055 ~N

Correct answer

D. 13055 ~N

Step-by-step solution

Mass of motor vehicle, m =1000 ~kg Banking angle, =30^ Coefficient of friction, =0.2 aligned & N =m g+f & Here f= N & N =m g+ N & N 3 2 =1000 10+0.2 N 1 2 & N [ 3 2 - 1 10 ]=10000 aligned Normal reaction force, N =13055 ~N
