A spherical capacitor consists of a spherical shell of radius b. This is concentric with a smaller conducting sphere of radius a. If charge given to inner sphere is +Q then energy of system is U1. Now if - Q charge is given to outer sphere also, energy of system is U2. What will be the potential energy of the system if - Q charge is given to outer sphere only (i.e. charge on inner sphere is zero)?

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
