4 The square of the period of oscillation (T) of a simple pendulum is directly
proportional to the length of the simple pendulum (1). If T = 8.4 s. then / = 36 cm
What is lif T = 7 s?

Answer:
Formula for the period of oscillation of a simple pendulum is
T=2π
g
L
Squaring both sides
T
2
=4π

g
L
g=4π

T

L
The error in the determination of g
g
Δg
=
L
ΔL
+2(
T
ΔT
).....(1)
here L=10 cm
ΔL=0.1 cm
T=0.5×100=50 s
ΔT=1 s
here T=
n
t
and ΔT=
n
Δt
So,
T
ΔT
=
n
Δt
As errors in both L and t are least count errors
hence from (1)
g
Δg
=

0.1
+2(
50

)
=0.005%
