A student measures length of a pendulum string to be 1 cm ± 0.05 cm and time period of oscillation to be 2 s ± 0.01 s. What will be the percentage error in measuring acceleration due to gravity if the following equation holds true? T = 2π L1/2 g-½ where L is the length of the pendulum and g is the acceleration due to gravity, T is the time period of oscillation(A) 6 %(B) 2%(C) 4 %(D) 1 %
