MP Board · Class 11 · Physics · Units and MeasurementsIf error in measuring mass is 2% and in velocity is 3%, the maximum percentage error in kinetic energy is:
📊Student Analytics & Stats
Total Attempts: 13
Accuracy Rate: 76.9%
Step-by-Step Solution
Kinetic Energy K = (1/2)mv^2. Fractional error dK/K = dm/m + 2*(dv/v) = 2% + 2*(3%) = 8%.
