1.	The magnetic field B shown in the figure is directed into the plane of the paper. ACDA is a semicircular conducting loop of radius r with the centre at O. The loop is now made to rotate clockwise with a constant angular velocity ω about an axis passing through O and perpendicular to the plane of the paper. The resistance of the loop is R. Obtain an expression for the magnitude of the induced current in the loop.
Answer» The magnetic field $B$ shown in the figure is directed into the plane of the paper. $ACDA$ is a semicircular conducting loop of radius $r$ with the centre at $O$ . The loop is now made to rotate clockwise with a constant angular velocity $ω$ about an axis passing through $O$ and perpendicular to the plane of the paper. The resistance of the loop is $R$ . Obtain an expression for the magnitude of the induced current in the loop.

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
