Assertion : The length of a simple pendulum is increases by `4%` the corresponding decrease in time period will be `2%`
Reason : `T = prop sqrt(1)`

Options

A. If both assertion and reason are true and the reasopn is correct explanation of the assertion
B. If both assertion and reason are true and but not the correct explanation of assertion
C. If assertion is true but the reason is false
D. If both assertion and reason are false

Answer

D

Explanation

As `T = sqrt(1)`
`(Delta T)/(T) = (1)/(2) ((Delta t)/(t)) = (1)/(2) xx 4% = 2%`
As length increases the time period will increases by `2%` it will net decreases
