How Do You Calculate the Force on a Charge in an Electric Field?

[rcmango]

Homework Statement

A charge of q = +7.50 µC is located in an electric field.

The x and y components of the electric field are Ex = 6.40 103 N/C and Ey = 8.80 103 N/C, respectively.

(a) What is the magnitude of the force on the charge?
in Newtons

(b) Determine the angle that the force makes with the +x axis.
in degrees°

Homework Equations

The Attempt at a Solution

I'm not sure how to use the x and y components to solve this.

not sure why i couldn't just use an equation like this: force per coulomb of charge is F/q0 = N/C

Use F=EQ to find the forces in the x and y components. Then it is just basic vector addition
