F = E x q
The Attempt at a Solution
I was told the direction of the E field should be pointing upwards but I have no clue as to why. I found the Force = 0.0012 N but not the direction.
So to find the electric field direction we only have to look at the charge of the particle?jackMybrain@ru said:Hi, I am not sure if anybody had ever told you this, but if you take law of elementary charges e.g. like charges repel and opposite attracts; which is basically indicates the direction of the attraction or repulsion force is felt, And electric field is just the opposite of it which is again said as, q+ has E outwards and q- has inward electric field. Therefore, you can see that the negative q or electron is pulled or attracted to another charge by 0.0012N in the direction of F but as it's Electric field is drawn to it because it is a negative charge, so Electric field is actually pointing upward which is where you electron is.
Look at the equation F=E*q. F and E are vectors, e is a scalar, it is negative now. What happens to the direction of a vector if you multiply it with a negative scalar? If the result, F, points downward, what is the direction of E?Raybulous said:Homework Statement

A charge does not feel its own electric field. When we say that a charged particle is placed in an electric field E, and a force acts on it, the force felt by the charge is F=qE, parallel or antiparallel with E, depending on the sign of the charge.Raybulous said:So to find the electric field direction we only have to look at the charge of the particle?
Hence the electric field is pointing towards the particle and not flowing in a constant direction?
The direction of the electric field is the direction of the force that a positive test charge would experience if placed in the field. This direction is represented by the direction of the electric field lines, which are drawn from positive to negative charges.
The direction of the electric field is determined by the relative positions of positive and negative charges. The field always points away from positive charges and towards negative charges.
Yes, the direction of the electric field can change depending on the positions and magnitudes of the charges in the system. For example, if an equal positive and negative charge are brought together, the electric field between them would cancel out and change direction.
The direction of the electric field is the direction of the force on a positive test charge, while the direction of current flow is the direction in which positive charges actually move. In most cases, these directions will be the same, but in certain situations, such as in a battery, the direction of current flow may be opposite to the direction of the electric field.
The direction of the electric field determines the direction and magnitude of the force on a charged particle. This force can cause the particle to accelerate or decelerate, change direction, or remain at a constant velocity. The behavior of charged particles is therefore heavily influenced by the direction of the electric field in their surroundings.
