1.	A monochromatic beam of light is incident at 60∘ on one face of an equilateral prism of refractive index n and emerges from the opposite face making an angle θ with the normal. For n=√3, the value of θ is 60∘ and dθdn=m. The value of m is.
Answer» A monochromatic beam of light is incident at $60^{\circ}$ on one face of an equilateral prism of refractive index $n$ and emerges from the opposite face making an angle $θ$ with the normal. For $n = \sqrt{3},$ the value of $θ$ is $60^{\circ}$ and $\frac{d θ}{d n} = m .$ The value of $m$ is.

A horizontal curve with superelevation e = 0.05 (note, e=tanβ ) has a posted speed limit of 60 km/h. For this speed limit, only those vehicles with Y/X ratio(in figure) greater than 2 and travelling at speeds greater than 1.2 times the speed limit, will overturn. However, with recent increase in truck traffic the speed limit needs to be modified such that only those vehicles with Y/X ratio greater than 3 and travelling at more than 1.2 times the speed limit will overturn. What should be the new speed limit?(in km/hr round off to integer) (with respect to the figure, assume that the vehicle is travelling into the plane of the paper).50
