During a camping trip, a student would like to carry water from the lake to their campsite. The student fills two non-identical buckets with water and attaches them to a L = 1.43 m long rod. Since the buckets are not identical, the student finds that the rod balances about a point l = 2.71 cm from its midpoint. The weight of the rod and empty buckets is negligible compared to the weight of the water. If the heavier bucket has mass my and the lighter bucket has mass mL, compute mH-mL/mL and express it as a percentage
