  • Q1 · Physics and Measurement · MEDIUM

    A physical quantity X is related to four measurable quantities a, b, c, and d as X = a²b³/(c√d). The percentage error in the measurement of a, b, c, and d are 1%, 2%, 3%, and 4% respectively. The percentage error in quantity X is:

  • Q3 · Physics and Measurement · HARD

    The period of oscillation of a simple pendulum is given by T = 2π√(L/g). If the length L is measured as 1.00 m with an error of 1 mm and time period T is measured as 2.00 s with an error of 0.01 s, then the maximum possible error in the value of g is:
