About 1%

Explanation:

For smaller change in amount of length we can say,
{TT}= (12){(LL)+(gg)}
As the change in g is zero,hence we can say change in time period= {(12)2} or 1%

Alternatively,
Let us assume that initial time period,
T=(2π)(lg)
Final Tf=(2π)
(1.02lg)
I.e equals to 1.0099T
So,change in Time period is 0.0099 or 0.99 % ~ 1%
