Objects 1 and 2 attract each other with a gravitational force of 36.0 units. if the mass of object 2 is tripled, then the new gravitational force will be units.

108N

Explanation:

According to law of gravitation which states that "the force

of attraction between two masses in a gravitational field is directly proportional to the product of their masses and inversely proportional to the square of their distance between them.

Mathematically, F = Gm1m2/r²

Where;

m1 and m2 are the masses of the object

G is the gravitational constant

r is the distance between the masses

If Objects 1 and 2 attract each other with a gravitational force of 36.0 units, we will have;

36 = Gm1m2/r²... (1)

If the mass of Object 2 is tripled, the gravitational force becomes

F = Gm1(3m2)/r²

F = 3Gm1m2/r²... (2)

Dividing equation 1 by 2, we will have;

36/F = {Gm1m2/r²}/3Gm1m2/r²

36/F = Gm1m2/r²×r²/3Gm1m2

36/F = 1/3

Cross multiplying we have

F = 36×3

F = 216N

Therefore, the gravitational force when the second object is tripled is 108N

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.

i believe the answer is electric potential.
