1.	A disk of radius a4 having a uniformly distributed charge 6 C is placed in the x-y plane with its centre at (−a2,0,0). A rod of length a, carrying a uniformly distributed charge 8 C is placed on the x-axis from x=a4 to x=5a4. Two point charges –7 C and 3 C are placed at (a4,−a4,0) and (−3a4,3a4,0) respectively. Consider a cubical surface formed by six surfaces x=±a2,y=±a2,z=±a2. The electric flux through this cubical surface is given by −n1ε0 V.m, where n is positive constant. Find the value of n.
Answer» A disk of radius $\frac{a}{4}$ having a uniformly distributed charge $6 C$ is placed in the x-y plane with its centre at $(\frac{- a}{2}, 0, 0)$ . A rod of length $a$ , carrying a uniformly distributed charge $8 C$ is placed on the x-axis from $x = \frac{a}{4}$ to $x = \frac{5 a}{4}$ . Two point charges $- 7 C$ and $3 C$ are placed at $(\frac{a}{4}, \frac{- a}{4}, 0)$ and $(\frac{- 3 a}{4}, \frac{3 a}{4}, 0)$ respectively. Consider a cubical surface formed by six surfaces $x = \pm \frac{a}{2}, y = \pm \frac{a}{2}, z = \pm \frac{a}{2}$ . The electric flux through this cubical surface is given by $- n \frac{1}{ε_{0}} V . m$ , where $n$ is positive constant. Find the value of $n$ .

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
