Question

The Centripetal force given by F = (mv²/r)
the mass (m), velocity (v) and radius (r) of an object after calculating errors are found to be
m=(0.5±0.005) kg
v=(10±0.01) ms⁻¹
r=(0.4±0.01) m
Calculate the percentage error in force.

Answer 1

Explanation:

∆F/F =( ∆m/m + 2∆v/v +∆r/r) ×100

=(0.005/0.5 + 2×0.01/10 + 0.01/0.4)×100

=(1/100 + 2/100+1/40)×100

=(3/100+1/40)× 100

=(6+5/200)×100

=(11/200)×100

= 5.5%
