The Force on a point charge from another point charge is along the Line connecting between the two charges. The direction will be towards the point charge if the two charges are different and away if they are same.
Now if you collection of Charges then it is vector sum of force due to each charge.

What determines the direction of polarization of a radiated electromagnetic field?
The polarization of an electromagnetic field is defined as the direction of its E field (electrostatic).
Why it is possible to define an electrostatic potential in a region of space that contains an electrostatic field?
Because there is an electrostatic field in that region of space
What should be the position of the antenna with respect to the direction of the transmitted radio waves so that the properly tuned in radio gives the better reception?
The antenna should be parallel to the electrostatic field of the wave, and perpendicular to its magnetic field and to its direction of propagation.
What can you determine from an electric field vector at one point?
From an electric field vector at one point, you can determine the direction of the electrostatic force on a test charge of known sign at that point. You can also determine the magnitude of the electrostatic force exerted per unit charge on a test charge at that point.
What Example of power flow by using pointing vector?
The direction of power flow is in the direction of the Poynting vector.The vector itself is the cross product of the Electrostatic field and the Magnetic field.P = E x H
Is it possible for electrostatic lines to intersect?
No. Lines of the electrostatic field don't intersect. A 'line' of the electrostatic field is an imaginary thing that shows the force on a tiny 'test charge' placed at any point. If two 'lines' intersected, it would mean that a tiny test charge at that point would feel a force in two different directions, and would have a choice of which way to go. But that doesn't happen ... the force at any point in the field is in a single, definite direction.
What will be the direction of charge if the gravitational force is equal to electrostatic force?
charge will be suspended it will not have any direction
An electric field is directed from left to right A proton is placed within the field What does the proton feel as a result of the field and why?
The 'direction' of the electrostatic (E) field is defined as the direction of the force on a positive charge in the field. The proton carries a positive charge, so when immersed in the E field directed from left to right, there is a force on the proton directed toward the right, and if you let go of the proton, it will go shooting off to the right.
What is capable of storing electrical energy in an electrostatic field?
condenser
How does electric field intensity form?
due electrostatic force
How will you shield a sensitive instrument from a strong electrostatic field?
By keeping it inside in a hollow conducting sphere. This process is known as electrostatic shielding.
What do you use in a vacuum to bend electronic beams?
Either an electrostatic field or a magnetic field. Each type is used in cathode ray tubes: generally, electrostatic in oscilloscopes, magnetic in television and computer CRTs.
