Where is the electric field of an isolated uniformly charged hollow metallic sphere greatest?

Contents

The electric field associated with a uniformly charged hollow metallic sphere is the greatest at: the sphere’s outer surface.

At what point is the electrical field associated with a uniformly charged hollow metallic sphere greatest?

The electric field at any point on the outer surface of the charged conducting spherical shell will be maximum.

At what point is the charge per unit area greatest on the surface of an irregularly shaped conducting solid?

It is greatest at the pointiest part of the irregular shaped surface. Examples are lightning rods they have the greatest charge per unit at its point. This is because all the charges are concentrated at the point.

Which is the most correct statement regarding the drawing of electric field lines?

Physics CRT Review Part 1

A B
The figure shown demonstrates charging by Polarization,
Both insulators and conductors can be charged by Contact
Which is the most correct statement regarding the drawing of electric field lines? Electric field lines never cross each other.
Electric field strength depends on Charge and distance

Do electrical conductors have electric charges that move freely?

Free charges move within the conductor, polarizing it, until the electric field lines are perpendicular to the surface.

Is the electric potential inside a conductor zero?

The electric field inside every conductor is ZERO ( when the arrangement remain as it is and in both above cases ) because the electric field due to induced charges is equal and opposite to electric field due to ‘inducing charge +Q’ at each and every point inside conductor.

Why do field lines never cross?

Electric field lines cannot cross. … This is because they are, by definition, a line of constant potential. The equipotential at a given point in space can only have a single value. If lines for two different values of the potential were to cross, then they would no longer represent equipotential lines.

At what point is the charge per unit area?

Surface charge density (σ) is the quantity of charge per unit area, measured in coulombs per square meter (C⋅m2), at any point on a surface charge distribution on a two dimensional surface.

Which best describes the electric field created by a positive charge?

The direction of the electric field of a positive charge is away from the charge. The direction of the electric field of a negative charge is towards the charge. Therefore, the electric field created by a positive charge describes its rays point towards the charge.

What does the strength of an electric field depend on?

The strength of the electric field depends on the source charge, not on the test charge. … Because an electric field has both magnitude and direction, the direction of the force on a positive charge is chosen arbitrarily as the direction of the electric field.

What type of material Cannot be charged?

Both the rods and the duster are made of insulating materials. Insulators prevent the electrons from moving and the charge remains static . Conductors , on the other hand, cannot become charged, as the electrons can move through them.
