Question

the gravitational force exerted by one object on another (A) is the same size as if each objects mass were located at its respective center of mass (B) is directly propertional to the distance between the two objects (C) does not depend upon the masses of the two subjects (D) causes both objects to accelarate at the same rate
I SAID D is it right?

Answer 1

"D" cannot be correct. This is true only if their masses are same.

"A" is the correct answer.
Remember where the distances are measured from? from their respective centers of masses.

Answer 2

like how its supposed to be directly propertional to the MASS between the two objects? i got a bit confused then i elimanated the other answers i was unsure if it was d or a because b nd c dnt fit in

Answer 3

what do you mean?

Answer 4

i mean i thought it was D because it couldnt be B or C and A i wasnt sure of

Answer 5

D is false because,
1) we know F for both objects is same
2) F = ma -> Newton's law
so, thy'd have same acceleration only if they have same masses.

Answer 6

but i read in my textbook that regardless of mass too objects will accelarate the same speed
or is it because mass and weight arent the same right

Answer 7

no.. what is the FORCE?
depends on the force and mass.. which ones are the same and what are the conditions.
In the given case, we do not know.
however, for masses falling down (Earth's gravity) then it will be same for two different objects will fall at same rate towards Earth. But the question asks about gravity between two objects. Earth does not accelerate towards a ball at 9.8m/s^2
follow?

Answer 8

i get it :) i see how that all makes sense
