In which direction does the electric field point at position directly east of a positive charge?
Yes. The electric field in physics is represented by a vector, it has three components governing the field strength in the up-down, left-right and forward-backwards directions.
What are field lines?

Define drift velocity?
it is defined as the average velocity with which the free eloctrons get drifted towards the positive ends of the conductor under the influence of an external electric field applied
What allows an electric charge to pass through it easily?
A conductor. This is due to free electrons.
A charge q is moving with a velocity v in free space write an expression for magnetic field produce at any point by this charge?
The magnetic field produced by this charge is B=( qz/r^2)v/c.

If a conductor is placed in a uniform electric field does the conductor gain any charge?
The conductor will not gain any charge that is not placed on it by you. However, the electric field will displace the free charges already within the conductor (by its nature) such that there will be a non-uniform surface charge density. Remember: a conductor must have zero electric field inside it, so the charges rearrange to cancel the external E-field. Again, this only repositions the existing charge, but it does not add or remove any charge.
Plasma?
an ionized gas consisting of positive ions and free electrons in proportions resulting in more or less no overall electric charge.
What is an electical current?
Electric current is simply the flow of free electrons in a conductor. It is usually defined as the rate of charge flow, because the free electrons represent an electric charge.
Can electric field lines intersect in free space?
No, because the electric field would not be defined at the intersection point.
One of the differences between electric and magnetic fields is that magnetic field lines always form closed loops?
One of the differences between electric and magnetic fields is that magnetic field lines always form closed loops. true
What are the characteristics of free radicals?
A free radical is a species that has unpaired electrons.Due to this , they are highly reactive. They can have either a positive charge, negative charge or no charge.

What happens when the electric field is applied to a very polar molecule?
dipole when placed in nonuniform electric field it experiences a net force if field is varying in direction but if field is nonuniform in magnitude then force depends on its posititon it may experience a torque again depends on depends on its posititon so it may translate as well as rotate
What happens if a free electron and a free proton are put into an electric field?
The proton will have greater acceleration. This is because the proton has a higher charge to mass ratio than the alpha particle. The proton has a +1 charge, as you know, and the alpha particle has a +2 charge because it has 2 protons in it. But the alpha particle also has a pair of neutrons fuesed to those 2 protons, so it has a 2 to 4 charge to mass ratio. The proton, with its 1 to 1 ratio of charge to mass, will have a greater acceleration in the same electric field.
