Answer 1

Answer:

if both the mass and radius of the earth, each decreased by 50%, the acceleration due to gravity doubled

Explanation:

we know that

g= GM/R^2

M become M/2( decreased by 50%)

R become R/2( " "" ")

so g'= GM/2÷(R/2)^2

g'=2GM/R^2

g'= 2g

Answer 2

Answer:

its 100%

Explanation:

we know

g=Gm/R^2

If radius half =R/2

and mass half=m/2

then new gravity

g =G (m/2)/ (R/2)^2

g=Gm(4)/2R^2

g=2Gm/R^2

hence g doubled

and if any thing doubles it mean it increases
