Answer:
Time period T = 
, where L is length and g is acceleration due to gravity.
, where L is length and g is acceleration due to gravity.since time period T 
, period increases by increasing the length of pendulam.
, period increases by increasing the length of pendulam.1% increase in length gives 2% increase in time period. Time period of pendulam is 1.02 s due to increase in length.
Clock based on this time period runs slow. Hence we are loosing time in a day that equals 24×60×60×0.02 seconds = 28 min 48 seconds
