Answer» A conducting rod AB of length L is rotating with a constant angular velocity in the plane of the paper about an axis perpendicular to the plane and passing through a point ‘C’ as shown in the diagram. A uniform magnetic field of magnitude B is perpendicular to the plane of the paper and into the plane. The velocities of A and B are perpendicular to the length of the rod AB. The emf induced between the ends of the rod is $\frac{1}{2} B V l \times \frac{1}{n}$ . Then n is ___

A parallel-plate capacitor having plate area A and plate separation d is joined to a battery of emf E and internal resistance R at t=0. Consider a plane surface of area A/2, parallel to the plates and situated symmetrically between them.

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
