1.	The blocks of mass m1=1 kg and m2=2 kg are connected by a spring and rest on a rough horizontal surface. The spring is unstressed. The spring constant of spring is K=2 N/m. The coefficient of friction between blocks and horizontal surface is 0.5. Now the left block is imparted a velocity u towards right as shown, then what is the largest value of u (in m/s) such that the block of mass m2 never moves (Take g=10 m/s2).
Answer» The blocks of mass $m_{1} = 1 kg$ and $m_{2} = 2 kg$ are connected by a spring and rest on a rough horizontal surface. The spring is unstressed. The spring constant of spring is $K = 2 N/m$ . The coefficient of friction between blocks and horizontal surface is 0.5. Now the left block is imparted a velocity $u$ towards right as shown, then what is the largest value of $u$ (in $m/s$ ) such that the block of mass $m_{2}$ never moves (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.

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
