e=V2/gr.

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

V^2/gr.

v-velocity of the vehicle,
g-gravitational force,
r-radius of the curve so right answer is option A.

e+f=(v*v)/gR
So directly prop to v.

Indirectly prop to radius and gravity.
Hence option A would be the answer.

It is directly proportional to the velocity square and inversely proportional to the radius of curvature.

directly proportional to velocity and width.
Inversely to the radius.

It seems wrong in acceleration.

e is the rate of superelevation.

h = e * B is the super elevation (which is proportional to width).

Directly proportional to the velocity and also inversely proportional to the radius of curvature.

Super elevation is inversely proportional to the radius.

E!=e B where e is the super-elevation.

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