1.	A massless spring S can be compressed 1 m by a force of 100 N in equilibrum. The same spring is placed at the bottom of a frictionless plane inclined at 30∘ to the horizontal. A block of 10 kg is released from rest at the top of incline and is brought to rest momentarily after compressing the spring by 2 m. If the speed of block just before it touches the spring is √10x m/s. Value of x is .[g=10 ms−2]
Answer» A massless spring $S$ can be compressed $1 m$ by a force of $100 N$ in equilibrum. The same spring is placed at the bottom of a frictionless plane inclined at $30^{\circ}$ to the horizontal. A block of $10 kg$ is released from rest at the top of incline and is brought to rest momentarily after compressing the spring by $2 m$ . If the speed of block just before it touches the spring is $\sqrt{10 x} m/s$ . Value of $x$ is . $[g = 10 {ms}^{- 2}]$

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
