# What forces can be either attractive or repulsive?

Contents

Electromagnetic forces can be either attractive or repulsive. They are long-range forces, which act over extremely large distances, and they nearly cancel for macroscopic objects. (Remember that it is the net external force that is important.)

## Which force is both attractive and repulsive in nature?

Electromagnetism is both an attractive and repulsive force between particles with a property called charge, which come in two varieties – positive and negative. Objects of like charge will have a repulsive effect on each other, while objects of unlike charges will have an attractive effect.

## Can both the electrostatic force and the gravitational force be either attractive or repulsive?

Yes, both the force between charges and the gravitational force between matter can be either attractive or repulsive.

## Which force can be attractive as well as repulsive?

A magnetic force can be both attractive as well as repulsive; i.e. like poles repel each other, whereas unlike poles attract each other. Q. Assertion :Assertion : Gravitational force is always attractive in nature, while electromagnetic force can be attractive or repulsive.

## Can a positive force be both attractive and repulsive?

A positive force can be both attractive and repulsive in nature. A negative force implies attractive nature.

## Which force is only attractive force?

Gravitational force is the only force which is always attractive.

## Is magnetic force attractive or repulsive?

magnetic force, attraction or repulsion that arises between electrically charged particles because of their motion. It is the basic force responsible for such effects as the action of electric motors and the attraction of magnets for iron.

## Why can electrostatic force be either attractive or 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 .

## Why can the electric force be attractive or repulsive where the gravitational force is always attractive?

What is the main difference between electrical and gravitational forces? Explanation: Electric forces can be attractive or repulsive because charges may be positive or negative. In the case for gravitational forces, there are only attractive forces because mass is always positive.

## Why can electric forces be attractive or repulsive but gravity is only attractive?

There are two “personalities” in electromagnetism, positive and negative. So they repel and attract. But there is only one “personality” in gravity, which is mass. So mass can only attract or repel, not both.

## What forces are non contact forces?

The three types of non-contact forces are gravitational force, magnetic force, electrostatic and nuclear force.

## Can gravitational force be attractive or repulsive?

Now, we know that the mass of the objects that is taken into consideration cannot be negative in nature. Hence, the nature of the gravitational force will always be attractive and not repulsive. Thus, we can conclude that gravitational force cannot be repulsive.

## Is gravitational force attractive or repulsive class 9?

We all know that all the forces in nature exist in opposites, but gravitational force is the only force that always attracts every object and never reples any.

## How do you know the force is attractive or repulsive?

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.

## Why are repulsive forces 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 …

## Can electrostatic force be repulsive?

The electric force between charged bodies at rest is conventionally called electrostatic force or Coulomb force. … If the charges have the same sign, the electrostatic force between them is repulsive; if they have different signs, the force between them is attractive.
