Answer» In a rigid wire frame ABCDEFA, as shown in the figure, a current I0 flows through the wire from A to F as shown in the figure. Radii of the three quarters, AB, CD and EF are $r_{1} = 3^{\frac{1}{4}} = 3^{\frac{1}{4}} m$ and $r_{3} = 1 m$ respectively with common center at O. All the wires are light except for the portion ED which have a mass of ‘m’ kg. If this loop is kept in a magnetic field of magnitude 2T which is directed along positive y-axis, torque acting on the loop is

In a rigid wire frame ABCDEFA, as shown in the figure, a current I0 flows through the wire from A to F as shown in the figure. Radii of the three quarters, AB, CD and EF are $r_{1} = 3^{\frac{1}{4}} = 3^{\frac{1}{4}} m$ and $r_{3} = 1 m$ respectively with common center at O. All the wires are light except for the portion ED which have a mass of ‘m’ kg.

If this loop is kept in a magnetic field of magnitude 2T which is directed along positive y-axis, torque acting on the loop 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
