What is the maximum percentage error?
(a) In measurement of kinetic energy if the percentage error in mass and speed are `1%` and `2%`, respectively.
(b) In measurement of pressure if maximum errors in the measurement of force and length of square plate are `3%` and `2%`, respectively.
In measurement of time period of simple pendulum if the percentage error in measurement of length and acceleraton due to gravity are respectively `2%` and `3%`
