# E-Field question?

Which of the following statements is true concerning the magnitude of the electric field at a point in space?

Electric field is energy per unit charge

Electric field is force per volt

Electric field and force are identical

Electric field is force times charge

Electric field is force per unit charge

Relevance

Electric field is energy per unit charge FALSE

Electric field is force per volt FALSE

Electric field and force are identical FALSE

Electric field is force times charge FALSE

Electric field is force per unit charge TRUE

Electric field

The strength or magnitude of the field at a given point

is defined as the force that would be exerted on a

positive test charge of 1 coulomb placed at that point;

the direction of the field is given by the direction of

that force.

E = F/Q = kQ/r²

Q = F/E F = QE

in Newtons/coulomb OR volts/meter

k = 1/4πε₀ = 8.99e9 Nm²/C²
