Answer» A spherical conductor A contains two spherical cavities. The total charge on the conductor itself is zero. However, there is a point charge $q_{b}$ at the centre of one cavity and $q_{c}$ at the centre of the other. A considerable distance r away from the centre of the spherical conductor, there is another charge $q_{b}$ . Force acting on $q_{b}, q_{c}$ and $q_{d}$ are $F_{1}, F_{2}$ and $F_{3}$ respectively. [Assume all charges are positive]

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
