Answer:
if the mass of one object is double the second one would be four times the mass
. no the distance between the two object wouldn't be doubled
.no the mass of one object would be doubled and second object would me four times

Answer:
Explanation:
a:i: From the relationship, (i) If the mass of one object (say body 1) is doubled, then Thus, the gravitational force between the two objects gets doubled. ... If the distance between the two objects is tripled, then Thus, the gravitational force between the two objects becomes one-ninth.
ii: The force F is inversely proportional to the distance between the objects. So if the distance between two objects is doubled then the gravitational force of attraction between them is reduced to one fourth of its original value.
iii:If the mass of both of the objects is doubled, then the force of gravity between them is quadrupled; and so on. Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces.
b:(m) = 50 g
(v) = 20 cm cube
(d) = m/ v =50 g /20cm cube
= 2.5 gcm cube -3
the substance will sink in water as it density more than of water.
HOPE IT HELPS YOU.
