Question:

Which statement describes the gravitational force and the electrostatic force between two charged particles? 1. the gravitational force may be either attractive or repulsive, whereas the electrostatic force must be attractive. 2. the gravitational force must be attractive, whereas the electrostatic force may be either attractive or repulsive. 3. both forces may be either attractive or repulsive. 4. both forces must be attractive.

Answers

Force is a vector quantity & must be treated accordingly; the electric force between two objects always acts along the line that connects their centers of charge ... Electric forces can be either attractive orrepulsive, but gravitational forces are always attractive (because objects can have either a positive or a negative charge, .

I believe the answer is. the gravitational force must be attractive, whereas the electrostatic force may be either attractive or repulsive. 

A) the objects attract each other

Explanation:

gravity always pulls no matter what. it does not repel

A. Large and pulls objects towards itself

Explanation:

Think about when you jump, you push yourself off the ground then gravity pulls you back down.

That takes out those last two answers.

Now let's think, is our planet large or small?

That's right, our planet is large.

So now we know the answer is the first one

A

Explanation:

Gravity and mass are directly related as a law of the universe. The bigger the mass of an object the higher the gravitational pull it has. Smaller objects will, therefore, be pulled towards the bigger objects. Part of the reason also is that bigger object have more inertia than smaller objects. Even though the smaller object may have some gravitational pull on the larger object, the lower inertia of the smaller object will cause it to be pulled and accelerate more towards the larger object than vice versa.

Answer : (B) it decreased by 1/4

Explanation :

It is given that :

The distance between twin satellites that were originally 150 meters apart are now 300 meters apart.

When the satellites are 150 m apart then the gravitational force is :

[tex]F=G\dfrac{m_1m_2}{(150\ m) ^2}[/tex]..........(1)

Similarly, when the satellites are 300 m apart then the gravitational force is :

[tex]F'=G\dfrac{m_1m_2}{(300\ m) ^2}[/tex]...........(2)

From eq (1) and (2)

[tex]\dfrac{F_c}{F_c'}=4[/tex]

[tex]F_c'=\dfrac{F_c}{4}[/tex]

So, the gravitational force between the twin satellites is decreased by 1/4.

Hence, the correct option is (b).

B or It decreased by 1/4.

Explanation:

Answer for edgenuity

is it a multiple choice question please provide options

The answer is B. 1/4. Distance between the two is greater resulting in less gravitational force.

A,
