Electric and magnetic (electromagnetic) forces can be attractive or repulsive, and their sizes depend on the magnitudes of the charges, currents, or magnetic strengths involved and on the distances between the interacting objects. Gravitational forces are always attractive.
Which of the following force is both attractive and repulsive?
Therefore, the electrostatic force is a non contact force which may be both attractive and repulsive in nature.
Which forces can be either attractive or repulsive quizlet?
Yes, both the force between charges and the gravitational force between matter can be either attractive or repulsive.
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 .
How do you know if the force is 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.
Is strong nuclear force attractive or repulsive?
The nuclear force is powerfully attractive between nucleons at distances of about 1 femtometre (fm, or 1.0 × 10−15 metres), but it rapidly decreases to insignificance at distances beyond about 2.5 fm. At distances less than 0.7 fm, the nuclear force becomes repulsive.
Can you be either a force of attraction or repulsion while <UNK> is only a force of attraction?
Second, gravitational forces are only attractive; electrical forces can be either attractive or repulsive.
What kind of objects would be attracted to an electrically charged object?
Any charged object – whether positively charged or negatively charged – will have an attractive interaction with a neutral object. Positively charged objects and neutral objects attract each other; and negatively charged objects and neutral objects attract each other.
What property underlies electrical forces?
Electrical forces depend on the property of matter called electric charge (or just charge, for short). The charge of protons and electrons are exactly the same size, but the proton is positively charged, while the electron is negatively charged.
What are repulsive forces?
Definitions of repulsive force. the force by which bodies repel one another. synonyms: repulsion. Antonyms: attraction, attractive force. the force by which one object attracts another.
Is electromagnetic attractive or repulsive?
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.
Why is gravity attractive force and not repulsive?
In the case of gravity, mediated by spin 2 particles, charge is mass, which is always positive. Thus, q1q2 is always greater than zero, and gravity is always attractive. For spin 0 force mediators, however, there is no restriction on the charges and you can very well have repulsive forces.
What is attractive and repulsive forces in physics?
Repulsion is a movement between two charges that are identical or similar. The power that exists between two electrons (negative charge). Attraction is a force between two charges that are distinct or unlike. … Repulsive forces occur only when atoms are very close to each other.
What kind of force can be attractive or repulsive school days?
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.
What is an attractive force?
Definitions of attractive force. the force by which one object attracts another. synonyms: attraction. Antonyms: repulsion, repulsive force. the force by which bodies repel one another.
