Answer 1

Answer:

acceleration due to gravity is doubled

Explanation:

given mass and radius are decreased 50% (i.e halved)

g = Gm1×m2/r² since both are halved

g' = G×1/2×m1×m2÷(1/2×r)²

g' = G×1/2×m1×m2÷1/4×r²

g' = 2×Gm1m2/r²

so, g' = 2g

the acceleration due to gravity is doubled

Answer 2

Explanation:

mass - weight radius - half of the cirle

decrease 50%

mass - 7. radius also 7

7 ×7 = 49
