A long horizontal rod has a bead which can slide along its length and initially placed at a distance L from one end A of the rod. The rod is set in angular motion about A with constant angular acceleration alpha. if the coefficient of friction between the rod and the bead is mu , and gravity is neglected, then the time after which the bead starts slipping is

Read the following paragraph and answer the following questions given below it : Construction of a compound microscope : (i) Acompound microscope consists of a metal tube fitted with two convex lenses at the two ends. These lenses are called the objective lens ( the lens directed towards the object ) and the eyepiece ( the lens directed towards the eye ). Both the lenses are small in size , but the cross section of the objective lens has a short focal length . the focal length of the eyepiece is more than that of the objective lens . (ii) The metal tube is mounted on a stand . thr principal axes of the objective lens and the eyepiece are along the same line . The distance between the object and objective lens can be changed with a screw . It is possible to change the distance between the objective lens and the eyepiece. Working : (i) The object to be observed is illuminated and placed in front of the objective lens. slightly beyond the focal length of the objective lens. it's real , inverted and enlarged image is formed by the objective lens on the other side. (ii) This intermediate image lies with in the focal length of the eyepiece. It serves as an object for the eyepiece. The eyepiece works as a simple microscope . the final image is virtual, highly enlarged and inverted with respect to the original object . It can be formed at the minimum distance of distinct vision from the eyepiece . The final image is observed by keeping the eye close to the eyepiece. Use: This microscope is used to observe blood cells , microorganisms , etc. State which distance is adjusted to observe the object with a compound microscope ?

A body is allowed to slide down a frictionless track from rest position at its top under gravity. The track ends in a circular loop of diameter D . Then, the minimum height of the inclined track (in terms of D ) so that it may complete successfully the loop is

A light rod of length 200 cm is suspended from the ceiling horizontally by means of two vertical wires of equal length tied on its end. One of the wires is made of steel and has area of cross-section 0.1 cm^2 and the order of brass of cross-sectional area 0.2 cm^2. An object of mass m is hung to the rod. (Y_"steel"=2xxY_"brass") At which distance from one end of the rod should a weight be hung to produce equal strains in both the wires?
