1.	A current carrying ring carrying a constant current 2π A has radius 1 m ,mass 23 kg and having 10 windings is free to rotate about its tangential vertical axis. A uniform magnetic field of it is applied perpendicular to its plane. The minimum angular velocity should be given to the ring in the direction shown, so that it can rotate 3π2 angle in that direction is √x rad s−1. Find x ( Give integer value).
Answer» A current carrying ring carrying a constant current $\frac{2}{π} A$ has radius $1 m$ ,mass $\frac{2}{3} kg$ and having $10$ windings is free to rotate about its tangential vertical axis. A uniform magnetic field of it is applied perpendicular to its plane. The minimum angular velocity should be given to the ring in the direction shown, so that it can rotate $\frac{3 π}{2}$ angle in that direction is $\sqrt{x} {rad s}^{- 1}$ . Find $x$ ( Give integer value).

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
