Is doubled
Becomes four times
Is reduced to half
Is reduced to a quarter
The mass of a body on Earth is 50 Kg (value of g on earth is g=9.8m/s2). If the value of acceleration due to gravity on the moon is 1/6 times the acceleration due to gravity on earth, then the mass of the body on the moon is
100
50/6
50
300
