Answer:
(d) increase by 100%
Explanation:
= initial mass of earth = m
= final mass of earth = (0.5) m
= initial radius of earth = R
= final radius of earth = (0.5) R
= initial acceleration due to gravity of earth = g
= final acceleration due to gravity of earth
initial acceleration due to gravity of earth is given as
Eq-1
Final acceleration due to gravity of earth is given as
Eq-2
Dividing eq-1 by eq-2

inserting the values

= 2 g
So there is 100% increase
Answer:
This isn't geography, so please put it as math.
Explanation:
