Question

· the centripetal force is given by F = m v2 / r, the mass(m), velocity (v) and radius(r) of the circular path of an object are 0.5 kg, 10m s-1 and 0.4 m respectively if m, v and r are measured to accuracies of 0.005 kg, 0.01 m s-1 and 0.01 m respectively, find percentage error in force acting on the body.

Answer 1

the centripetal force is given by F=mv^2 /r the mass (m),velocity(v)and radius(r) of the circular path of an object are 0.05kg , 10ms^-1 and 0.4m respectively if m,v and r are measured to accuracies of 0.005kg,0.01ms^-1 and 0.01m respectively.
