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?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?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.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?
