How does angle help find electric force from mass and gravity?

[daewoo]

I have quiz coming up soon, and my teacher hinted that I had to find a formula for electric force using variables of mass, gravity, and an angle.
"Fe" = eletric force, |E| = field strengh, q= charge in Columbs.

To find eletric force all i know is Fe = kq1q2/r^2 , Fe = |E|q

anyone got any ideas on how knowning a angle would help?

Gravity has nothing to do with electric forces, so I don't think you'll find any connection.
