At sea level a metal cylinder is found to balance exactly against standard masses adding up to 10kg on a beam balance. The cylinder and the same set of standard masses are carried to a hill station where the local value of acceleration due to gravity is 9.75ms−2, while at sea level it is 9.80ms−2.
(i) What mass will the beam balance indicate for the cylinder at the hill station? Give a reason for your answer.
(ii) The cylinder is now weighed with a spring balance at the hill station. Calculate the weight recorded.
(iii) Determine the percentage decrease in the weight of the cylinder when it is taken from sea level to the hill station.
