What else can I help you with?
Does electric force require that objects touch?
No, electric force does not require objects to touch in order to act on each other. Objects with electric charge can exert attractive or repulsive forces on each other even when they are not in physical contact.
Is the direction of the electric force on a charge is tangent to the field line?
No, the direction of the electric force on a charge is along the electric field vector and not necessarily tangent to the field line. The force on a charge will be in the same direction as the electric field if the charge is positive, and opposite if the charge is negative.
What happens when a charged particle is moved along an electric field line?
When a charged particle is moved along an electric field line, it experiences a force in the direction of the field line. This force causes the particle to accelerate in the direction of the field line if the particle has the same charge as the field line, or decelerate if the charges are opposite.
Do two positive charges repel each other from a distance or repel each other only when they touch?
Two positive charges will repel each other from a distance due to the electric force between them. They do not have to touch in order to feel the repulsive force. This repulsion is a fundamental property of electric charges.
What two forces can act on an object without having to actually touch the object?
Gravitational force and electromagnetic force can act on an object without having to physically touch it. Gravitational force is the attraction between two masses, while electromagnetic force is the force between electric charges or magnets.
What is the difference between magnetic force and electric force?
The force is just one aspect of magnetism. For example, there is a magnetic field all around a magnet. Of course they are related, but "magnetism" is a wider term for the entire phenomenon - it may relate to the force, to the magnetic field, or to a few other things.
Is the electric force a conservative force?
Yes, the electric force is a conservative force.
What is the relationship between an electric force and an electric field?
An electric force is the force on an electric charge or an electrically charged object when immersed in an electric field.
Does any force act on a point charge is moving in a electric field at right angle to the field line?
Yes. A force acts on the charge perpendicular to the plane defined by the charge velocity and the electric field line of force. The Electric field is is equivalent to and magnetic field E=cB, where c is the speed of light. This causes a power field P= cqvxB = c(qvxB) = cForce. Maxwell was the first to predict that light was a form of electricity when he found this relationship, E=cB. Maxwell noticed that light and electric fields had the same speed, c.
Does an electromagnet use an electric force or a magnetic force?
it uses electric force
What is the symbol for electric force?
The symbol for electric force is ( F_e ).
Why electric line of force can not have sudden break?
Electric field lines represent the continuous flow of electric field from one point to another. If there were a sudden break in the electric field line, it would imply a sudden discontinuity in the electric field strength, which is not physically possible. This is because electric field lines are a visual representation of the direction and strength of the electric field, which must be continuous to maintain the conservation of electric field flux.
