1.	An infinitesimally small bar magnet of dipole moment Pm is pointing and moving with the speed v in the x-direction. A small closed circular conducting loop of radius a and negligible self–inductance lies in the y-z plane with its centre at x = 0, and its axis coinciding with the x-axis. The resistance of the loop is R. Assume that the distance x of the magnet from the centre of the loop is much greater than a. The force opposing the motion is ∝1xy. Value of y is ___
Answer» An infinitesimally small bar magnet of dipole moment $P_{m}$ is pointing and moving with the speed v in the x-direction. A small closed circular conducting loop of radius a and negligible self–inductance lies in the y-z plane with its centre at x = 0, and its axis coinciding with the x-axis. The resistance of the loop is R. Assume that the distance x of the magnet from the centre of the loop is much greater than a. The force opposing the motion is $\propto \frac{1}{x^{y}}$ . Value of y 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
