The force exerted on a charged particle by an electric field is expressed as:

$\overline{){\mathbf{F}}{\mathbf{=}}{\mathbf{q}}{\mathbf{E}}}$, where q is a charge on particle and E is the electric field.

**Part (a)**

We've been given F.

We also know that the electric force takes the direction of the electric field.

Suppose an electric field exerts a 4.65 x10^{-17} N westward force on an electron.

Part (a) Find the horizontal component of the electric field in NC, taking east as positive.

Part (b) Find the horizontal component of the force that this field exerts on a proton, taking east to be positive
