If displacement of a body s = (200 ± 5) m and time taken by it t = (20 + 0.2) s, then find the percentage error in the calculation of velocity.
Share
Percentage error in measurement of displacement= 5/200×100
Percentage error in measurement of time = 0.2/20×100
Maximum permissible error = 2.5 + 1 = 3.5%
