Two blocks A and B of equal masses are released from an inclined plane of inclination 45∘ at t=0. Both the blocks are initially at rest. The coefficient of kinetic friction between the block A and the inclined plane is 0.2 while it is 0.3 for block B. Initially the block A is √2 m behind the block B. When will their front faces come in a line?

Two blocks A and B of equal masses are released from an inclined plane

1.	Two blocks A and B of equal masses are released from an inclined plane of inclination 45∘ at t=0. Both the blocks are initially at rest. The coefficient of kinetic friction between the block A and the inclined plane is 0.2 while it is 0.3 for block B. Initially the block A is √2 m behind the block B. When will their front faces come in a line?
Answer» Two blocks $A$ and $B$ of equal masses are released from an inclined plane of inclination $45^{\circ}$ at $t = 0$ . Both the blocks are initially at rest. The coefficient of kinetic friction between the block $A$ and the inclined plane is $0.2$ while it is $0.3$ for block $B$ . Initially the block $A$ is $\sqrt{2} m$ behind the block $B$ . When will their front faces come in a line?

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
