Q. A 7.5 m wide two-lane road on a plain terrain is to be laid along a horizontal curve of radius 510 m. For a design speed of 100 kmph, super-elevation is provided as per IRC: 73- 1980. Consider acceleration due to gravity as 9.81 m/s2. The level difference between the inner and outer edges of the road (in m, up to three decimal places) is
