 \nEXPERIMENT  \nUse of Vernier Callipers to  \n(i)measure diameter o a small spherical/cylindrical body,  \n(iij)measure the dimensions of a given regular body of known massand hence to determine its density;and  \n(iii)measure the internal diameter and depth ofa given cylindricalobjectlike beaker/glass/calorimeterand hence to calculate its volume.  \n# APPARATUS AND MATERIAL REQUIRED          \n\nVernier Callipers,Spherical body,such as a pendulum bobor a glassmarble,rectangular block of known mass and cylindrical object likea beaker/glass/calorimeter  \nD  \n# ESCRIPTION OF THE MEASURING DEVICE\n\n1.A Vernier Calliper has two scales-one main scale and a Vernierscale,which slides along the main scale.The main scaleand Vernierscale are divided into small divisions though of differentmagnitudes.  \nThe main scale is graduated in cm and mm.It has two fixed jaws,Aand C,projected at right angles to the scale.The sliding Vernier scalehas jaws(B,D)projecting atright angles to it and also the main scale  \nand a metallic strip(N).The zero ofmain scale and Vernier scale coincidewhen thejaws are made to touch eachother.The jaws and metallic strip aredesigned to measure the distance/diameter of objects.Knob Pis used toslide the vernier scale on the mainscale.Screw Sis used to fix the vernierscale at a desired position.  \nc  \nM  \n2.The least count of a common scaleis lmm.It is difficult to furthersubdivide it to improve the leastcount of the scale.A vernier scaleenables this to be achieved.  \nFig.E1.1 Vernier Calliper  \n1  \nP  \n   \nThe difference in the magnitude of one main scale division (M.S.D.)and one vernier scale division(V.S.D.)is called the least count of theinstrument,as it is the smallest distance that can be measured usingthe instrument.  \nnV.S.D.=(n-1)M.S.D.  \nFormulas Used  \n(a)Least count of vernier callipers  \nwhere mis(b)Density of a rectangular boits mass,lits length,bits breadth and hthe height.  \nh  \n(c)  The volume of a cylindrical (hollow)object  \nwhere h'is its internal depth,D is its internal diameter and risits internal radius.  \nP  \nROCEDURE  \n(a)Measuring the diameter of a small spherical or cylindricalbody.  \n1.Keep the jaws of Vernier Callipers closed.Observe the zero mark ofthe main scale.It must perfectly coincide with that of the vernierscale.Ifthis is not so,account for the zero error for all observations tobe made while using the instrument as explained on pages 26-27.  \n2.Look for the division on the vernier scale that coincides with adivision of main scale.Use a magnifying glass,if available andnote the number of division on the Vernier scale that coincideswith the one on the main scale.Position your eye directly over thedivision mark so as to avoid any parallax error.  \n3.Gently loosen the screw to release the movablejaw.Slide it enoughto hold the sphere/cylindrical body gently(without any unduepressure)in between the lowerjaws AB.Thejaws should be perfectlyperpendicular to the diameter of the body.Now,gently tighten thescrew so as to clamp the instrument in this position to the body.  \n4.Carefully note the position of the zero mark of the vernier scaleagainst the main scale.Usually,it will not perfectly coincide with  \n   \nany of the small divisions on the main scale.Record the main scaledivision just to the left of the zero mark of the vernier scale.  \n5.Start looking for exact coincidence of avernier scale division withthat of a main scale division in the vernier window from left end(zero)to the right.Note its number(say)N,carefully.  \n6.Multiply 'N'by least count of the instrument and add the productto the main scale reading noted in step 4.Ensure that the productis converted into proper units(usually cm)for addition to be valid.  \n7.Repeat steps 3-6 to obtain the diameter of the body at differentpositions on its curved surface.Take three sets of reading ineach case.  \n8.Record the observations in the tabular form [Table E1.1(a)]withproper units.Apply zero correction,if need be.  \n9.Find the arithme","cbCaikK3zae7eh9t","https://ap.wps.com/l/cbCaikK3zae7eh9t","pdf",3236234,37,"English","#
