Answer:The weight of an object is directly proportional to the mass of the earth and inversely proportional to the square of the radius of the earth. i.e.
Weight of a body ∝
R
2
M
Original weight W
o
=mg=mG
R
2
M
when hypothetically M becomes 4 M and R becomes
2
R
Then weight becomes
W
n
=mG
(
2
R
)
2
4M
=(16mG)
R
2
M
=16×W
o
The weight will become 16 times the present weight.
