Answer:
what what what I what what what
]Least count, LC=0.01cm
Here the negative zero error of callipers =5×0.01=0.05cm and it should be added to final reading.
Main scale reading, MSR=2.4cm and VSD=6
So total reading means the diameter of sphere R=MSR+(VSD×LC)+ zero error =2.4+(6×0.01)+0.05=2.51 cm
