1.	A solid uniformly charged fixed non conducting sphere of total charge Q and radius R contains a tunnel of negligible diameter. If a point charge −q of mass ′m′ is released at rest from point P as shown in figure then its velocity at the surface of the sphere is found to be √(nqQ12πε0Rm).

Answer» A solid uniformly charged fixed non conducting sphere of total charge $Q$ and radius $R$ contains a tunnel of negligible diameter. If a point charge $- q$ of mass $^{'} m^{'}$ is released at rest from point $P$ as shown in figure then its velocity at the surface of the sphere is found to be $\sqrt{(\frac{n q Q}{12 π ε_{0} R m})}$ . Find the value of $n$ (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
