A smooth circular road of radius r is banked for a speed `v=40 km//hr`. A car of mass m attempts to go on the circular road. The friction coefficient between the tyre and the road is negligible. The correct statements are:

Options

A. The car cannot make a turn without skidding.
B. If the car turns at a speed less than `40 km//hr`, it slips down.
C. f the car turns at the correct speed of `40 km//hr`, the force by the road on the car is equal to `mv^(2)//r`.
D. If the car turns at the correct speed of `40 km//hr`, the force by the road on the car is greater than mg as well as greater than `mv^(2)//r`.

Answer

B, D
