What happen if a charged particle is placed in an electric field?
In an electric field a charged particle, or charged object, experiences a force. If the forces acting on any object are unbalanced, it will cause the object to accelerate. If two objects with the same charge are brought towards each other the force produced will be repulsive, it will push them apart.
Will a positive charge follow the electric field lines if free to move?
A positively charged particle always moves along the electric lines of forces.
What happens to the field lines when a charged particle is placed in a close proximity to another charged particle?
When charged particles are close enough to exert force on each other, their electric fields interact. This is illustrated in the Figure below. The lines of force bend together when particles with different charges attract each other. The lines bend apart when particles with like charges repel each other.
In which case does an electric field do positive work on a charged particle?
In the case where a negative change moves in a direction opposite to the electric field, q is negative and d is also negative. Therefore, W = (-q)E(-d) = qEd. The electric field does positive work in this case.
When a positive charge moves in the direction of the electric field from A to B what happens to the electrical potential energy associated with the charge?
When work is done on a positive test charge to move it from one location to another, potential energy increases and electric potential increases.
Which of the following is true when a positive charge moves in the direction opposite to an electric field?
the field does negative work on it and the potential energy decreases. When a positive charge moves opposite to the direction of the electric field, the field does positive work on it and the potential energy decreases. C.
Will a charged particle always move in the direction of electric field if free to move justify?
If charged particle is positive, and at rest. Electric field lines are straight then only it will move in the direction of electric field.
Do particles follow electric field lines?
Yes, electric field lines represent the path followed by a test charge in that field. The test charge must be 1 C electric charge. So if the charge is positive 1 C the electric force will be equal to electric field.
When a positive charge moves to a positive plate the potential energy of charge?
The potential energy for a positive charge increases when it moves against an electric field and decreases when it moves with the electric field; the opposite is true for a negative charge. Unless the unit charge crosses a changing magnetic field, its potential at any given point does not depend on the path taken.
Will a charge particle always move in an electric field?
Originally Answered: A charge particle is free to move in an electric field. Will it always move along electric line of force? No. If the particle is given a non-zero, finite velocity in a direction not coinciding with a line of force, then the net motion of the particle is not along the line of force.
What is the direction of a charge on a particle?
A free charge will always move along the line of force but the direction depends on the nature of the charged particle. Positive charge will move along the direction of line of force ( electric field line) and negative charge will move opposite to the direction of line of force Depends on the type of charge.
How do positive and negative charges move in a circuit?
Positive charge will move along the direction of line of force ( electric field line) and negative charge will move opposite to the direction of line of force Depends on the type of charge. Positive charge will travel along the ‘lines of force’ or, electric field lines. Negative charge will travel opposite to those.
How do you know if a particle will follow the field line?
If the particle’s velocity has a component normal to the field line, then it will not follow the field line. If a particle starts from rest and the electric field lines are straight, then the particle will follow the electric lines.
