Are attractive 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 attractive force negative?
That’s all right,but I want to know whenever we use a work done by an attraction force we use a negative sign,viz: the gravitational potential.It is written in books that the gravitational potential is negative because the work to bring an object from infinity to the gravitational field is done by the gravitational …
What will happen if the attraction force is negative?
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. … The size of the force is proportional to the value of each charge.
Is negative force attractive in nature?
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.
What is negative force?
A negative force is an opposing force acting on an object against the implemented force. … A ‘negative’ force is the opposite of what you choose to be the positive direction. Magnitude of a force is never negative but direction can be negative that is opposite direction.
What does positive force mean?
a (of an electric charge) having an opposite polarity to the charge of an electron and the same polarity as the charge of a proton. b (of a body, system, ion, etc.) having a positive electric charge; having a deficiency of electrons.
