A $7.5 \mathrm{~m}$ wide two-lane road on a plain terrain is to be laid along a horizontal curve of radius $510 \mathrm{~m}$. For a design speed of $100 \mathrm{kmph}$, super-elevation is provided as per IRC: 73 -1980. Consider acceleration due to gravity as $9.81 \mathrm{~m} / \mathrm{s}^{2}$. The level difference between the inner and outer edges of the road (in $\mathrm{m}$, up to three decimal places) is
