# Is negative force attractive in nature?

Contents

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.

## Is a negative force attractive or repulsive?

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).

## Can a positive force be attractive?

If the particles are both positively or negatively charged, the force is repulsive; if they are of opposite charge, it is attractive.

## Are negative forces repulsive?

According to Coulomb, the electric force for charges at rest has the following properties: Like charges repel each other; unlike charges attract. Thus, two negative charges repel one another, while a positive charge attracts a negative charge. The attraction or repulsion acts along the line between the two charges.

## Why is negative potential attractive?

U=−rGMm​. 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).

## What is negative force?

A negative force is the force acting on an object against the applied force. The applied force here is positive that is aimed in the right direction whereas a negative force acts in the left direction. An example of negative force is deceleration, where the speed of a moving object decreases due to gravitational force.

## Is a positive force can be both attractive and repulsive in nature?

Regarding force (c)A positive force can be both attractive and repulsive in nature. Explanation: The force is repulsive if the particles are both positively or negatively charged; it is attractive if they are of opposite charge.

## How do you know if a force is positive or negative?

Work can be either positive or negative: if the force has a component in the same direction as the displacement of the object, the force is doing positive work. If the force has a component in the direction opposite to the displacement, the force does negative work.

## What is the nature of positive force?

Positive, Negative and Zero work done

1. 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.

## Is gravitational force always attractive?

Gravitational force is always attractive based on the traditional understanding of matter, which has a positive mass.

## What does negative potential signify?

The potential at any point is always an indicator of how much more potential energy a coulomb would have compared to when it’s at some reference point. So, if the potential is negative, it means the coulomb at that point would have less potential energy compared to when it’s at the reference point.

## What happens if potential is negative?

A negative potential energy means that work must be done against the electric field in moving the charges apart!
