If Fg=mg=ma and, Fg(planetX)=1/5Fg(earth) 
then the time would be 5x of the time as gravity is acceleration. So 3.9s*5=19.5s 
As the force of gravity is less, then the acceleration of masses is also less, therefore it will take more time for the object to fall by the factor of the force of gravity difference

False. Weather has periods of change, imagine a rainy day and a sunny day, it is a change in weather
        
             
        
        
        
Answer:
If the mass of one of the objects is tripled, then the force of gravity between them is tripled. ... Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces
