According to Coulomb’s Law, the force between two charged objects is related to _____. the distance separating them the mass of
2 answers:
Answer:
the inverse of the square of the distance separating them
Explanation:
As we know that two charges are separated by some distance from each other than that force is given as
here we know that
[tex]q_1, q_2[/tex = two different point charges
r = distance between two charges
so here we know from above formula that electrostatic force between two charges depends on the product of two charges and inversely depends on the square of the distance between two charges
so correct answer will be
the inverse of the square of the distance separating them

Answer:
The angular speed of the system increases.
The moment of inertia of the system decreases.
Explanation:
As we know that the girl is going towards the center of the circle so here the moment of inertia of the girl is given as
here we know that
r = position of the girl from the center of the disc
now we know that the girl is moving towards the center so its distance will continuously decreasing
So the moment of inertia of the girl will decrease
Now we know that that with respect to the center of the disc there is no torque on the disc + girl system
So here we can use angular momentum conservation
So we have
since moment of inertia is decreasing for the system
so angular speed will increase
