A 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 firctioncoefficient between the tyre and the road is negligible.

A

the car cannot make a turn without skidding.

B

If the car turns at a speed less than 40 km/hr, it will slip 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
