Answer» A rectangular frame $ABCD$ made of a uniform metal wire has a straight connection between $E$ and $F$ made of the same wire as shown in figure. $AEFD$ is a square of side $1 m$ and $EB = FC = 0.5 m$ . The entire circuit is placed in a steadily increasing uniform magnetic field directed into the plane of the paper and normal to it. The rate of change of magnetic field is $1 {T s}^{- 1}$ . The resistance per unit length of the wire is $1 Ω m^{- 1}$ . Find the magnitude of the current in the segment $EF$ .

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
