v^2/225R.
= 75 x 75/227 x 1000.
= 0.025.
=1in40.

Yes @Yugananth

V^2/225R is the correct formula.

Danjah said:   9 years ago
here 1000 m is the length of curve, not radius.

Why used 75% in que not mention mixed traffic?

It is the right answer, it will use v^2/225r.

ANS (A).

e = V^2/225R.
e = 0.025 = 1 in 40.

Prashant said:   10 years ago
1000 m is length of curve here, not radius.

RAVINDRA said:   9 years ago
The given answer is true, don't confuse it.

Biswa said:   1 decade ago
e = (0.75v)^2/Rg.

v in m/s.

Ans: 1 in 40.
