The percentage error in the measurement of g is ( . Given that g= 4 ^2 ~L ~T ^2 , ~L =(10 0.1) cm , T =(100 1) s ):

Options

  1. A2 %
  2. B5 %
  3. C3 %
  4. D7 %

Correct answer

C. 3 %

Step-by-step solution

Given: aligned g & = 4 ^2 ~L ~T ^2 ~L & =(10 0.1) cm , and T & =(100 1) s aligned Hence, error in measurement of g is aligned g g & = L L +2 T T & = 0.1 10 100+2 1 100 100 & =3 % aligned
