    Charge on pendulum due to electric field

    I used tan(theta) for both of the tension components, then used (mg) and (E) to find q and got the right answer...is that the right way?

    Charge on pendulum due to electric field

    I have a similar question, and I'm getting confused on the tension part of the forces. Would the 3 forces be the horiz/vert of the tension force, then the electric field force? So you get Tcos(theta) + mg-Tsin(theta) + Eq = 0 ...then solve for q? I'm pretty sure this is wrong...any guidance?

    Force on a Charged Object in a Field

    ooops I posted on the wrong problem I think haha
