1.	Figure shows a uniform circular loop of radius a having resistance per unit length ρ placed in a unifrom magnetic field B perpendicular to plane of figure. A uniform rod of length 2a & resistance R moves with a velocity v as shown. Find the current in the rod when it has moved a distance a2 from the centre of circular loop. Given B=√3,a=2,v=3,ρ=94π,R=2√3 all in SI units.
Answer» Figure shows a uniform circular loop of radius $a$ having resistance per unit length $ρ$ placed in a unifrom magnetic field $B$ perpendicular to plane of figure. A uniform rod of length $2 a$ & resistance $R$ moves with a velocity $v$ as shown. Find the current in the rod when it has moved a distance $\frac{a}{2}$ from the centre of circular loop. $Given B = \sqrt{3}, a = 2, v = 3, ρ = \frac{9}{4 π}, R = \frac{2}{\sqrt{3}}$ all in SI units.

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
