A smooth circular rod 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 type and the road is negligible, The correct statements are :

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

If 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`
