Question 15 and 16 are case study based questions and are compulsory Attempt
any 4 such parts from each questions. Each question carry I mark
15.In physics, attempts are made to make the measurement of physical quantities
with the best possible accuracy. However, the measurement of the physical
quantities are never 100 %correct. There is always some degree of uncertainty in
the measurement of physical quantities due to various reasons. The measure of
degree of uncertainty in the measurement of physical quantity is known as error.
