The formula for electric field is E = k * Q / r^2, where E is the electric field strength, k is the Coulomb's constant, Q is the charge, and r is the distance from the charge.
How is the electric field calculated?
The electric field is calculated by dividing the product of the charge and the Coulomb's constant by the square of the distance from the charge.
Can you derive the electric field formula?
Yes, the electric field formula can be derived from Coulomb's Law which describes the force between two charges.
What is the unit of electric field?
The unit of electric field is Newton per Coulomb (N/C).
What does the electric field represent?
The electric field represents the force experienced by a charged particle in the presence of other charges.
What happens to the electric field as distance increases?
As distance increases, the electric field strength decreases.
How does the magnitude of charge affect the electric field?
The magnitude of charge directly affects the electric field strength. Greater the charge, stronger the electric field.
What is the relationship between electric field and electric potential?
Electric field is the negative gradient of electric potential.
Can electric field exist in a vacuum?
Yes, electric field can exist in a vacuum as it is a property of space itself.
What is the direction of the electric field produced by a positive charge?
The electric field produced by a positive charge points away from the charge.
What is the direction of the electric field produced by a negative charge?
The electric field produced by a negative charge points towards the charge.
Is electric field a vector or scalar quantity?
Electric field is a vector quantity as it has both magnitude and direction.
Can electric field lines cross each other?
No, electric field lines cannot cross each other.
What is the direction of electric field lines?
Electric field lines always point in the direction of the electric field at a given point.
How is electric field measured experimentally?
Electric field can be measured experimentally using a device called an electroscope.
