1.	Assertion : The period change in time period is `1.5% ` if the length of simple pendulum increases by `3%`. Reason : Time period is dinesty proportional to length of pendulum.A. If both the asseration and reason are true and reason is a true explanation of the asseration.B. If both the asseration and reason are true but the reason is not the correct explanation of asseration.C. If the asseration is ture but reason is false.D. If both the asseration and reason are false.
Answer» Correct Answer - c Time period of simple pendulum of length `l` is ` T = 2 pi sqrt((I)/(g))` `rArr T prop sqrt(1)` `:. (Delta T)/(T) = (1)/(2) (Delta I)/(I) ` `(Delta T)/(T) = (1)/(2) xx 3 = 1.5%`
