e=v2/gR,
So answer A is correct because question is asking incorrect statement, but superelevation is directly proportional to the square of velocity and inversely proportional to acceleration due to gravity and radius of curvature.

As super elevation e+f=v^2/ (g.r) so it is directly proportional to the design speed option b is incorrect because the speed of vehicles is mentioned there in the statement not the design speed of the vehicle will differ for the different vehicle so it is incorrect.
Because s.e can be made on design speed.
Because s.e can be made on design speed.

Super elevation =V*2/gR=F/W<=b/2h.
So, the answer is b.
So, the answer is b.

e=V2/gr.
So, I think all option is true. But, e is directly proportional to the square of the velocity of the vehicle.

Directly proportional to velocity square I guess that's why it's incorrect here!

e=tan (θ) = opp/adj = h/b = central rise/width.
So super elevation is inversely proportional to width of pavement. But they have given as directly prop. So the answer is A.
