A circular road of radius r is banked for a speed of v = 40km/h. A car of mass m attempts to go on the circular road. The friction coefficient between the tyre and the road is negligible. Then-
(A) The car cannot make a turn without skidding
(B) If the car turn at a speed less than 40km/h, it will slip down.
(C) If the car turns at the correct speed of 40km/h the force by the road on the car is equal to mv2 /r
(D) If the car turns at the correct speed of 40 km/h, the force by the road on the car is greater that mg as well as greater than mv2 /r
