Can positive force be both attractive and repulsive in nature?

Can a positive force be both attractive and repulsive?

If the particles are both positively or negatively charged, the force is repulsive; if they are of opposite charge, it is attractive. … Unlike the gravitational force however, the Coulomb (or electric) force may be either attractive or repulsive, depending on the signs of the charges and .

Is positive force always repulsive?

If the product q1q2 is positive, the force between the two charges is repulsive; if the product is negative, the force between them is attractive.

Is repulsive force positive or negative?

When the charges have opposite sign, the force is attractive (negative F), while if both charges have the same sign, the force is repulsive (positive F).

Why is repulsive energy positive?

You would have learnt this thing in chemistry (In Atom Structure, you would have calculated energy of electrons for different energy levels b/w electron & proton(nucleus)), that attractive force reduces the energy of the electrons and repulsive force increases the energy of electrons) So since energy corresponding to …

Are electromagnetic forces attractive or repulsive?

Electromagnetic force is a special force that affects everything in the universe because it has an infinite-range attractive, like gravity; it is also a repulsive force which acts between charged particles.

Can gravity be both attractive and repulsive?

Both in the Newton theory of gravitation and in the General Theory of Relativity the gravitational force is exclusively attractive one. However, the quantization of gravity shows that the gravitational forces can also be repulsive [3].

Which of these forces is only attractive in nature?

Grade 9. 1) gravitational force is the only attractive force.

Which force is only attractive?

Gravitational force is the only force which is always attractive.

Is negative force attractive in nature?

Like charges repel and unlike charges attract. Coulomb’s law describes a force of infinite range which obeys the inverse square law, and is of the same form as the gravity force. … A negative force implies an attractive force. The force is directed along the line joining the two charges.

What is the nature of positive force?

Positive Work : If a force displaces the object in its direction, then the work done is positive. The example of this kind of work done is motion of ball falling towards ground where displacement of ball is in the direction of force of gravity.

Why do attractive forces have negative potential energy?

This is a negative value for two reasons; the force acting between them is attractive, and the zero of potential energy is at infinite separation. This is a negative result if the force between the two charges is attractive (they are opposite) and positive if it is repulsive (the charges are similar).

Is positive force attractive?

If both the interacting particles are positively or negatively charged, then the force is repulsive. If both the interacting particles are of opposite charges then the force is attractive in nature. Coulomb’s law describes this nature of electric charges.

Is negative potential attractive?

Remember the rule: Opposites attract; Likes repel. A positive charge would be repelled by something that already has a positive potential, while a negative charge would be attracted to the very same object.
