Webb9749/01/AJC/2024Prelim 1 A student attempts to determine the radius of a steel ball by using a metre rule to measure four similar balls in a row. The student estimates the position on the scale to be as follows: X = (1.00 ± 0.05) cm Y = (5.00 ± 0.05) cm What is the radius of a steel ball together with its associated uncertainty?
