In an experiment of simple pendulum, the errors in the measurement of length of the pendulum (L) and time period (T) are 3 % and 2 % , respectively. The maximum percentage error in the value of L T^2 is

Options

  1. A5 %
  2. B7 %
  3. C8 %
  4. D1 %

Correct answer

B. 7 %

Step-by-step solution

Maximum percentage in the value of L T^3 aligned & = L L 100 %+2 T T 100 % & =3+2 2=7 % aligned
