1.	A wire loop enclosing a semicircle of radius R is located on the boundary of a uniform magnetic field B . At the moment t=0 , the loop is set into rotation with constant angular acceleration α about an axis O . The clockwise emf direction is taken to be positive and the magnitude of variation of emf as a function of time is denoted by E .

Answer» A wire loop enclosing a semicircle of radius $R$ is located on the boundary of a uniform magnetic field $B$ . At the moment $t = 0$ , the loop is set into rotation with constant angular acceleration α about an axis $O$ . The clockwise emf direction is taken to be positive and the magnitude of variation of emf as a function of time is denoted by E . If $t_{1}$ and $t_{2}$ are the time required to complete first half and second half circle respectively then, which of of the following options are correct? ( $E_{n}$ is the inducede emf produced in nth half rotation.)

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
