TARGET PublicationsUse of Vernier CallipersPrecautions:i. While holding object in the jaws, do not exert undue pressure on it. The jaws should just touchthe object.ii. Take number of readings at different positions of the sphere as well as cylinder.iii. The upper jaws should just touch the inner diameter of hollow cylinder.iv. The coinciding division of vernier scale should be taken accurately, if required magnifyingglass can be used.Space for calculation:Std. XI Sci. : Physics Practical Handbook 4
