Answer: The acceleration due to gravity Planet A is

Explanation: We are given an object having mass 12 kg. It weights 69 N on Planet A, which means that some force of gravity is acting on the object on Planet A.
To calculate Force of gravity on Planet A, we use the equation for force of gravity:

where, F = Weight = 69 N =

m = Mass = 12 kg
g = Acceleration due to gravity
Putting the values in above equation, we get:
