Answer:
force at the top will be 388 N which is nearly equal to 389
option (b) is correct
Explanation:
We have given velocity of the moving car v = 10 m/sec
Radius of the circular section r = 30 m
Mass of the passenger m = 60 kg
Acceleration due to gravity
At the top normal force is given by
So force at top will be
So force at the top will be 388 N which is nearly equal to 389
So option (b) is correct
