Electric Force vs Gravitational Force

What is Coulomb's law?

• Coulomb's law is the study of static electricity in motion

• Coulomb's law is based on the relationship between voltage and current

• Coulomb's law only applies to conductive materials

• Coulomb's law states that the force between two point charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.

What is the formula for the gravitational field?

• g = -GM/r

• g = -GM/r^2

• g = GM/r^2

• g = -GM*r^2

Define electric field.

• The electric field is a scalar field that describes the force experienced by a charged particle at any given point in space.

• The electric field is a constant force experienced by a charged particle at any given point in space.

• The electric field is a vector field that describes the force experienced by a charged particle at any given point in space.

• The electric field is a type of magnetic field that describes the force experienced by a charged particle at any given point in space.

How does the electric force between two charges compare to the gravitational force between two masses?

• The electric force between two charges is much weaker than the gravitational force between two masses.

• The electric force between two charges is much stronger than the gravitational force between two masses.

• The electric force between two charges and the gravitational force between two masses are equal in strength.

• The electric force between two charges has no effect on the gravitational force between two masses.

What are the similarities between electric force and gravitational force?

• Both forces are attractive only

• Both forces are stronger at shorter distances

• Both forces are not affected by the mass of the objects

• The similarities between electric force and gravitational force include following an inverse square law and being conservative forces.

What are the differences between electric force and gravitational force?

• The differences between electric force and gravitational force are that electric force is between charged particles, can be attractive or repulsive, and is much stronger than gravitational force.

• Gravitational force is between charged particles, while electric force is between celestial bodies

• Electric force is weaker than gravitational force

• Electric force is only attractive, while gravitational force is only repulsive

Explain the concept of electric field lines.

• Electric field lines are imaginary lines that represent the direction and strength of the electric field at different points in space.

• Electric field lines always point towards the positive charge

• Electric field lines only exist in a vacuum

• Electric field lines are physical lines made of conductive material

How does the direction of the electric field compare to the direction of the gravitational field?

• The direction of the electric field can be either towards or away from the charged object, while the direction of the gravitational field is always towards the mass.

• The direction of the electric field is always towards the charged object, while the direction of the gravitational field is always away from the mass.

• The direction of the electric field is always away from the charged object, while the direction of the gravitational field is always towards the mass.

• The direction of the electric field is always perpendicular to the charged object, while the direction of the gravitational field is always parallel to the mass.

What are the units of measurement for electric force and gravitational force?

• Newtons (N)

• Watts (W)

• Kilograms (kg)

• Meters (m)

Explain the concept of inverse square law and how it applies to both electric force and gravitational force.

• The inverse square law applies to both electric force and gravitational force, where the force between two point charges or masses is inversely proportional to the square of the distance between them.

• The force between two point charges or masses is directly proportional to the square of the distance between them

• The inverse square law applies to sound waves, not electric or gravitational force

• The inverse square law only applies to electric force, not gravitational force
