Question

IF radius of earth shrinks by 1.5% mass remain the same value of acceleration due to gravity changes by

Answer 1

Answer:

Explanation:

g = G M / R2

as, R is decreased by 1.5%

So, new Radius , R' = R - 0.015 R = 0.985R

So, new g, g' = G M / (0.985R) 2

= 1.0306 G M/ R2

So, change = 0.0306

% change = 3 % (approx)

Answer 2

Answer:

As the radius decreases to 1.5% the acceleration due to gravity will be increase by 1/(0.985*0.985)

and thus becomes about 1.03 times it's previous value, i.e an increase around 3%
