Equation e + f = v2/127 R.
Thus e directly proportional to velocity and inversely proportional to radius of curvature which
is right.
So incorrect answer is option C inversely proportional to acceleration due to gravity.
Thus e directly proportional to velocity and inversely proportional to radius of curvature which
is right.
So incorrect answer is option C inversely proportional to acceleration due to gravity.

Superelevation(E) = Rate of superelevation(e)* Width of pavement(B).
So E directly proportional to B,
So the correct option will be 'B' .
So E directly proportional to B,
So the correct option will be 'B' .

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

Actually it is not directly proportional to width of pavement. Because,
Superelevation (e) = tan (tita) = sin (tita) = opp side /hyp= E/ width of pavement.
Superelevation (e) = tan (tita) = sin (tita) = opp side /hyp= E/ width of pavement.

Is it they are considering directly proportional to square of velocity?

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