What happens to field strength when two unlike equal charges overlap one another?

The field is stronger between the charges. In that region, the fields from each charge are in the same direction, and so their strengths add. The field of two unlike charges is weak at large distances, because the fields of the individual charges are in opposite directions and so their strengths subtract.

What is a combination of two charges with equal charge magnitude but opposite signs?

An electric dipole is a combination of two point charges having equal magnitude but opposite signs. An electric dipole is a set of two point charges of equal magnitude, but opposite sign.

What are the equipotential surfaces of a uniformly charged sphere?

For an isolated point charge, the equipotential surface is a sphere. i.e. concentric spheres around the point charge are different equipotential surfaces. In a uniform electric field, any plane normal to the field direction is an equipotential surface.

How does the magnitude of the electric field at point 1 compare to the magnitude of the electric field at point 2?

What can you say about the field at point 1 compared with the field at point 2? The field at point 1 is larger, because the field lines are closer together in that region. A negative point charge is in an electric field created by a positive point charge.

What is the electric field between two opposite charges?

The net electric field due to two equal and oppsite charges is 0. This is only true if the two charges are located in the exact same location.

Which of the two charges Q1 and q2 is greater in magnitude?

From the graph, it can be seen that net potential due to the two charges is positive everywhere in the region left of charge Q1. Therefore, the magnitude of potential due to charge Q1 is greater than that due to Q2. Therefore, the absolute value of charge Q1 is greater than that of Q2.

What is the relationship between equipotential surfaces and electric field lines?

An equipotential surface is a three-dimensional version of equipotential lines. Equipotential lines are always perpendicular to electric field lines. The process by which a conductor can be fixed at zero volts by connecting it to the earth with a good conductor is called grounding.

When there are two or more charges the electric fields of each individual charge?

When there are two or more charges, the shape of the electric field gets altered. The electric field of each individual charge combines by repelling or attracting.

How do you find the electric field of a spherical surface?

Find the electric field a distancezfrom the center of a spherical surface of radius R, whichcarries a uniform surface charge density σ. Treat the case z< R(inside) as well as z> R(outside). Expressyour answer in terms of the total charge qon the surface. Figure2.4.

What is the Coulomb field of a point charge?

The total electric field at Pis equal to the sum of the zcomponents of the electric fieldsgenerated by the two point charges: When z» dthis equation becomes approximately equalto which is the Coulomb field generated by a point charge with charge2q.

What is the electric field at the aparticular point?

The electric field at aparticular point is a vector whose magnitude is proportional to the total forceacting on a test charge located at that point, and whose direction is equal tothe direction of the force acting on a positive test charge. The electric field,generated by a collection of source charges, is defined as

How do you find the electric field inside a charged shell?

Inside the shell, z < r and consequently the electric field is equal to. Thus the electric field of a charged shell is zero inside the shell. The electric field outside the shell is equal to the electric field of a point charge located at the center of the shell.
