# The centripetal force is given by $F = \large\frac{Mv^2}{r}$ The mass, velocity and radius of the circular path of an object are 0.5 kg, 10 m $s^{–1}$ and 0.4 m respectively. Find the percentage error in the force. Given: m, v and r are measured to accuracies of 0.005 kg, 0.01 m $s^{–1}$ and 0.01 m respectively.
