– I Will Ensure That No External Force Is Added To The System
-I Will Ensure That No Pallarax Error In Taking The Readings Of The Stop Watch

1bi)
Period Of Oscillation Of A Simple Pendulum Is The The Taking The Pendulum To Complete One Oscillation

1bii)

1bii)
NaA=15
NB=20
TA=1.5sec

But TA= TA/NA
TA =Ta*Na
=1.5*15
TA=22.5sec

The Tb= TB/Nb
But TA=TB=22.5sec
Tb=22.5/20
=1.125sec
