Which statements correctly describe the effect of distance in determining the gravitational force and the electrical force? check all that apply.

the gravitational force has an infinite reach.
the electrical force has an infinite reach.
the gravitational force is inversely proportional to the distance.
the electrical force is inversely proportional to the distance.
the gravitational force is inversely proportional to the square of the distance.
the electrical force is inversely proportional to the square of the distance.

--"The gravitational force is inversely proportional to the square of the distance"

--"The electrical force is inversely proportional to the square of the distance".

Explanation:

The gravitational force is represented by the following equation

Where r is the distance between both objects, G is the gravitational constant and M represents the mass of each object.

The electrical force is represented by the following equation

Where r is the distance between both charges and , K is the constant of the Coulomb law and q represents the charge of each object

Note that both forces are inversely proportional to the distance squared.

Since the distance between the objects is inversely proportional to the electric or gravitational force, then if the distance r increases, both forces decrease.

Therere When the distances r tend to infinity, the forces tend to zero.

Therefore statements 1 and 2 are incorrect.

The correct affirmations are 5 and 6

*"The gravitational force is inversely proportional to the square of the distance"

*"The electrical force is inversely proportional to the square of the distance".

The correct answers are "The gravitational force is inversely proportional to the square of the distance" and "The electrical force is inversely proportional to the square of the distance".

Explanation:

The expression for the electrostatic force is as follows;

Here, F is the electrostatic force, k is constant, Q,q are the charges and r is the distance between the charges.

The expression for the gravitational force is as follows;

Here, F is the gravitational force, G is universal constant, M,m are the masses and r is the distance between the masses.

The electrostatic force and the gravitational force follows inverse square law.

The electrostatic force and the gravitational force are inversely proportional to the square of the distance. They are directly proportional to the product of the charges and the product of the masses respectively.

the earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.
