1.	A man starts walking from the point P(−3,4), touches the x− axis at R, and then turns to reach at the point Q(0,2). The man is walking at a constant speed. If the man reaches the point Q in the minimum time, then 50(PR)2+(RQ)2 is equal to
Answer» A man starts walking from the point $P (- 3, 4),$ touches the $x -$ axis at $R,$ and then turns to reach at the point $Q (0, 2) .$ The man is walking at a constant speed. If the man reaches the point $Q$ in the minimum time, then $50 (P R)^{2} + (R Q)^{2}$ is equal to

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
Anair-cored solenoid with length 30 cm, area of cross-section 25 cm2and number of turns 500, carries a current of 2.5 A. The current issuddenly switched off in a brief time of 10−3s. How much is the average back emf induced across the ends of theopen switch in the circuit? Ignore the variation in magnetic fieldnear the ends of the solenoid.
