The formula is;
e + f= Bv2/gR.
e + f= Bv2/gR.

Rate of super elevation e=E/B, & E=eB.
E = super elevated hight or superelevation.
But e = v^2/127R,
i.e E = v^2B/ 127R.
From this equation, we can conclude that super elevation (E) is directly proportional to the velocity of the vehicle, while the rate of superelevation (e) is inversely proportional to the width of the pavement (B).

Superelevation is directly proportional to the velocity of the vehicle. So, Option A is correct.

Here, e is directly proportional to v^2 not to V.

I think option A is the right answer for this.

Option A will be the answer.
Because, super elevation (e) = tan(theta)= Tangent/Base.
So, if base ie. The width will increase then Tangent ie. The rise of the outer edge will be increased to maintain as tan (theta). After that theta (angle of inclination) will be the same.
So, e= tan theta dependable on theta and not dependable on the width

B is the right option.
Agree @Anuj statement.

For the total amount of superelevation, A, C, and D are correct.
So, incorrect can only be B as it is proportional to the square of the speed and not the speed only.

It is directly proportionel to quare of velocity not directly proportionl to single velocity.
