The length of a cylinder is measured with a meter rod having least count `0.1 cm`. Its diameter is measured with Vernier calipers having least count `0.01 cm`. Given that length is `5.0 cm` and radius is ` 2 cm`. Find the percentage error in the calculated value of the volume.A. `1%`B. `2%`C. `3%`D. `4%` |

Answer» Correct Answer - C Volume of cylinder `V=pir^2l` Percentage error in volume `(triangleV)/(V)xx100=(2triangler)/(r )xx100+(trianglel)/(l)xx100` `=(2xx(0.01)/(2.0)xx100+(0.1)/(5.0)xx100)=(1+2)%=3%` |
