1.	YDSE is carried out with two thin sheets of thickness 10.5 mm each and refractive indices μ1=1.5 and μ2=1.4 covering the slits S1 and S2 respectively. If white light of range 4000 ∘A to 7800 ∘A is used then which wavelength will form minima exactly at the centre O of the screen
Answer» YDSE is carried out with two thin sheets of thickness 10.5 mm each and refractive indices $μ_{1} = 1.5 a n d μ_{2} = 1.4$ covering the slits $S_{1}$ and $S_{2}$ respectively. If white light of range 4000 $^{\circ}$ to 7800 $^{\circ}$ is used then which wavelength will form minima exactly at the centre O of the screen

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.
