Answer» Figure shows a conducting rod of negligible resistance that can slide on a smooth U-shaped rail made of wire of resistance 1 $Ω m^{- 1}$ . Position of the conducting rod at $t = 0$ is shown. A time-dependent magnetic field $B = 2 t$ (tesla) is switched on at $t = 0$ . The magnitude of the force required to move the conducting rod at a constant speed of $5 c m / s$ at the some intstant of $t = 2 s$ is equal to 1000 $x \times 10^{- 3} N$ , where $x$ is (Answer upto 2 decimal places).

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
