1.	The blocks of mass m1=1 kg and m2=2 kg at rest are connected by a spring of spring constant k=2 N/m. The coeffcient of friction between blocks and horizontal surface is μ=12. Now the block of mass m1 is imparted a velocity u towards block of mass m2 as shown, then the largest value of u (in m/s) such that the block of mass m2 never moves is (Take g=10ms−2)
Answer» The blocks of mass $m_{1} = 1 k g$ and $m_{2} = 2 k g$ at rest are connected by a spring of spring constant $k = 2 N / m$ . The coeffcient of friction between blocks and horizontal surface is $μ = \frac{1}{2} .$ Now the block of mass $m_{1}$ is imparted a velocity $u$ towards block of mass $m_{2}$ as shown, then the largest value of $u$ (in $m / s$ ) such that the block of mass $m_{2}$ never moves is (Take $g = 10 m s^{- 2}$ )

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. If the displacement current through this surface as a function of time is given as:id=EnRe−tdε0ARWhere, ε0 is the permittivity of free space.The value of n is :
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
