Answer:
g/9
Explanation:
length of the pendulum = L
time period on the earth = T
Time period on the planet = 3T
Let the acceleration due to gravity on the earth is g and on the planet is g'.
Use the formula for the time period of a simple pendulum for the time period on earth
.... (1)
Time period on the surface of planet is
.... (2)
Divide equation (2) by equation (1)
g' = g/9
Thus, the acceleration due to gravity on the planet is g /9
