Magnitude of force on charge.

  1. Jan 15, 2008 #1
    1. The problem statement, all variables and given/known data

    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°

    2. Relevant equations

    3. 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
