where l is length of pendulum and g is acceleration due to gravity .
Putting the given values for first place
Putting the values for second place
Dividing these two equation
T = 2.66455 s.
Answer:
F) The acceleration due to gravity is g/27
Explanation:
According to Newton gravitational law, the gravitational acceleration is directly proportional to the planet mass and inversely proportional to the square of distance.
Since our new planet has a mass of one-third of Earth's and radius 3 times of Earth's. This means the new planet is lighter and further away from the distance. This means g is first reduced by 3 due to smaller mass and then reduced by 9 due to square of 3 times the distance.
The gravitational acceleration on this new planet must be
So F) is the correct answer
