Question

If both, the mass and radius of the earth, each
decreases by 50%, the acceleration due to
gravity would
(A) Decrease by 50% (B) Increase by 50%
(C) Remains the same (DY Increase by 100%​

Answer 1

Answer:

g=Gm2/R2

so G(1/2m)2/(1/2R)2

which is equal to Gm2/R2

So the correct option is (c) Remains the same

Thanks

I hope this helps you

Answer 2

Answer:

D option is the correct answer

Explanation:

g = GM/R^2

for 50% decrease of both

New g will be G(2M/(R/2)^2

which will be 2GM/R^2 which is double the original gravity

% increase = [(2g-g)/g]*100% = 100%

Hope this help:-)
