Given equation,

#T= 2pi sqrt(L/g)#

or, #(dT)/T = 1/2 (dL)/L#

or, #(dT)/T 100 = 1/2 (dL)/L 100#

given, #(dL)/L 100 =2#

So, #(dT)/T 100= 1#

That means,there will be #1%# increase in time period of the pendulum.

So, #dT =1/100 T#

Now,in #1# day,nos of seconds are, #1*24*3600=86400#

So, #dT = 1/100 * 86400=864s=14.4 min#
