(2) To find the diameter of the sphere (VSRXLC) Diameter,d-MSR+ (cm) Slno: Dimension MSR VSR (cm) (div) (VSRXLC) (cm) Diameter (d) Mean d= cm Radius of the sphere,r%3Dd/2 cm Volume of the sphere,V=(4/3). 3 cm m3 Procedure: 1. Calculate the LC of vernier calipers. 2. Measure length,breadth&thickness of a rectangular block and diameter of the given sphere by using vernier calipers. 3. Find MSR and VSR for each physical quantity. 4. Calculate the total reading by using the formula MSR+(VSRXLC). 5. Find the volume of block using the equation V=lbh& volume of the sphere V=(4/3) IIr 6. Repeat the experiment 4 or 5 times. Precautions: 1. The movement of vernier scale on main scale should be smooth 2. Take measurements of diameter by changing the orientation of the body 3. Notice the readings carefully to avoid error due to parallax Sources of error 1. In poor quality of vernier 2. Parallax may be there in taking the observations alipers ws may not perpendicular scales 3 -m Result: Volume of the rectangular block,V= Volume of the sphere,v= m 523t n (2) To find the diameter of the sphere (VSRXLC) Diameter,d-MSR+ (cm) Slno: Dimension MSR VSR (cm) (div) (VSRXLC) (cm) Diameter (d) Mean d= cm Radius of the sphere,r%3Dd/2 cm Volume of the sphere,V=(4/3). 3 cm m3 Procedure: 1.
