The acceleration due to gravity on the surface of moon is 1.7 ms–2. What is the time period of a simple pendulum on the surface of moon if its time period on the surface of earth is 3.5 s? (g on the surface of earth is 9.8 ms–2)

g E = 9.8 m/s
g M = 1.7 m/s
t E = 3.5 s
t M = ?
g = v - u /t
9.8 = v - 0 /3.5
9.8 × 3.5 = v
34.3=v
now;
gM /v= 1/t
34.3/ 1.7 = t
= 20.17 seconds.

on earth
---------------------------------
T = 2π √ l/g
-------------
we know that T = 3.5 s
3.5 = 2π √ l/g
taking sq on both sides
(3.5)² = (2π)² x l/g
T²
l = ----------- x g
(2π)²
(3.5)²
l = --------- x 9.8
(6.28)²
solving this we get length = 3.04 m
-------------------------------
on moon substituting the length in the time period formula we get
T = 2π √ l/g
T = 2π ( √ 3.04/1.7)
T = 2π (√1.7)
T = 6.28 x 1.33
T = 8.35 s
----------------------------------------------------------------------------------------
there fore the time period of a simple pendulum on the surface of moon will be 8.35 s or approximately = 8.4 s
