Question

30. The length of a cylinder is measured with a metre
rod having least count 0.1 cm. Its diameter is
measured with vernier calliper having least count
0.01 cm. Given that length is 5.0 cm and radius
is 2.00 cm. The percentage error in the
calculated value of the volume will be
(a) 1%
(b) 2%
(c) 3%
(d) 4%​

Answer 1

Explanation:

Volume of cylinder V=πr2l

Percentage error in volume

△V/V×100=2△r/r×100+△l/l×100

=(2×0.012.0×100+0.15.0×100)=(1+2)%=3%
