What is an electric field?
A region around a charged particle or object within which a force would be exerted on other charged particles or objects.
1 of 5
Is electric field strength a vector or scalar quantity?
Electric field strength is a vector quantity.
2 of 5
How is the direction of the electric field strength linked to the direction of the electric force?
The direction of the electric field strength E, is the same as the direction of the electric force F.
3 of 5
How do you calculate electric field strength using the force experienced in the electric field and the charge of an object in the electric field?
The Electric Field Strength (NC^-1) = Force experienced in an electric field (N) / Charge of object in electric field (C). E = F / Q.
4 of 5
What direction do field lines always point in?
Away from positive charge towards negative charge.
