Let us assume the acceleration due to gravity on the other planet to be g'
Then, g'= G*5M/2R(squared) = 5/4 G*M/R(squared) = 5/4g
M= mass of earth, R= radius of earth g= acceleration due to gravity on earth
Now that is going to be 5/4 times the accleration due to gravity on earth.
Then, g'= G*5M/2R(squared) = 5/4 G*M/R(squared) = 5/4g
M= mass of earth, R= radius of earth g= acceleration due to gravity on earth
Now that is going to be 5/4 times the accleration due to gravity on earth.
