1.	If displacement of a body s = (200 pm 5) m and time taken by it t = (20 pm 0.2) s, then find the percentage error in the calculation of velocity.
Answer» Solution :Percentage error in MEASUREMENT of DISPLACEMENT `= (5)/(200) xx 100` Percentage error in measurement of time `= (0.2)/(20) xx 100` `:.` MAXIMUM permissible error `= 2.5 + 1 = 3.5%`
