Question

How is electric field strength a vector?

Answer 1

I guess kinda in the same way that crocodiles are known for being really strong at biting down on stuff but very weak at opening their mouths, which is why people wrestle them.

Answer 2

A vector has magnitude AND direction.

Answer 3

For electric field strength we have this formula,

\[\vec{F} = q \vec{E}\]

Now since charge is a scalar quantity, and force is a vector quantity, thus, electric field strength must be a vector...

Answer 4

This is the mathematical reason...

Answer 5

Now let's have a more practical reason... here is the figure of electric field lines of a positive charge..



Notice their direction
