Question

What will be the percentage change in the acceleration due to gravity of earth if its radius expand by 40% and mass decrease by 40%​

Answer 1

Answer:

As per question final radius = 1.4 times initial radius

And final mass =1.8 times initial mass

Using proportionality we can write final g

s

=

1.96

1.8

times initial g

s

Thus acceleration due to gravity decrease by approximately 8.16%
