Answer» The capacitance of a parallel plate capacitor is $C_{0}$ when the plates have air between them. This region is now filled with a dielectric slab of dielectric constant $K$ and capacitor is connected with a battery of emf $E$ and zero internal resistance. Now slab is taken out, then during removal of slab: $1.)$ Charge $E C_{0} (K - 1)$ flows through the cell. $2.)$ Energy $E^{2} C_{0} (K - 1)$ is absorbed by cell. $3.)$ The energy stored in the capacitor is reduced by $E^{2} C_{0} (K - 1)$ . $4.)$ The external agent has to do $E^{2} C_{0} (K - 1)$ amount of work to take out the slab. Select the correct phenomenon happening during the process:

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
