Electrostatics
What would be the ratio of electric flux through a spherical surface surrounding only one out of four equally spaced identical positive point charges to that through a larger concentric spherical surface encompassing all four?
0 : 0
16 : 1
1 : 4
4 : 1
What does an electric field inside a parallel plate capacitor primarily depend on?
The material between the plates only.
The distance between the charges only.
The speed at which charges move through the circuit.
The charge on the plates and the area of the plates.
What happens to the electric field strength as you move further away from an isolated point charge?
It fluctuates periodically.
It increases.
It remains constant.
It decreases.
Given four point charges forming vertices ABCD in square configuration AB=BC=CD=DA=q others p=-0 q calculate force exerted charged particle located just outside square mid-way AB CD axis
Each charge contributes individually squared distance away
Resultant horizontal forces cancel vertical components combined via Pythagorean theorem
Dominant influence comes from closest pair leading to attraction toward them
Net force directed towards center since like-charges repel opposites attract
What is the electric potential energy of two point charges and that are 0.5 m apart in a vacuum?
Consider a point charge Q placed at the origin and a point P located at a distance R from it. What expression accurately describes the magnitude of the electric field, E, at point P and its direction?
kQ
kQ/R
Q/R
If an electron experiences an electric potential difference while moving from point A to B, what can we say about its kinetic energy at B compared to A?
Smaller than at A
Larger than at A
Electrons do not have kinetic energy
The same as at A

A proton is moved closer to a fixed positive charge; how does this affect the electric potential energy of the system?
It increases.
It stays constant.

In a region with an electric field described by vector function E = , where k is constant, what path should a positive test charge follow starting from origin to maintain constant potential?
