The centripetal force acting on a body of mass m moving with speed v along a circular path of radius r is given by
`F = (mv^(2))/(r)`
If the values of m , v and r are measured as `0.5` kg , `10 ms^(-1)` and `0.4` m respectively to the accuracies of `0.005` kg , `0.01 ms^(-1)` and `0.01 ` m respectively , calculate the percentage error in the force acting on the body.

Answer

`3.6 %`
