As we have learnt,

Simple Pendulum -

T=2\pi \sqrt{\frac{l}{g}}

l\rightarrow length\, of\, pendulum

g\rightarrow acc^{n}\, due\, to\, gravity.

- wherein

 

T = 2\pi\sqrt{\frac{l}{g}}\;\; \therefore T \propto \sqrt l

Percentage increment in T = \frac{1}2 (percentage increment in l) = 0.5%.


Option 1)

Increase by 1%

Option 2)

Increase by 0.5%

Option 3)

Decrease by 0.5%

Option 4)

Increase by 2%
