1.	A thin 1 m long rod has a radius of 5 mm. A force of 50 pikN is applied at one end of determine its Young.s modulus. Assume that the force is exactly known. If the least count in the measurement of all lengths is 0.01 mm, which of the following statements is false?
Answer» The maximum value of `gamma` that can be determined is `10^(14)N//m^(2)`. `(Delta gamma)/(gamma)`GETS minimum contribution from the uncertainty in the length. `(Delta gamma)/(gamma)` gets its maximum contribution from the uncertainty in strain. The FIGURE of merit is the LARGEST for the length of the rod Answer :1
