Long day, stupid mistake but that gave me .10164N but I'm still confused as whether the tension is the vector sum of Mg and Horizontal electric force. Also how that applies to the angle.

So that makes q \frac{ \sigma}{2 \epsilon_0} = 5.0824486*(10*10) and mg =.01*9.8=.098 so would the tension equal the vector sum of the mg and electric field

The range between the two values worries, is that right?

I've wondered how you would explain how a sailboat moves in a way explained by physics. How the energy from the wind is transferred from the sail to the centerboard or the hull itself.

Sorry it is .01kg and 0.3 uC/m2 Well I think at least the electric field coming off the wall = Sigma/[2(Epsilon)] The charge from the from the mass = q/[(4)(Pi)(r^2)(Epsilon)] mg= 1N but honestly from there is was just guesswork and I can't remember what I put. (I'm doing this problem...

Homework Statement A ball of mass .01 hangs 1.5m with a charge of 3u(micro)C from a thin string attached to the top of a wall with uniform charge density .3uC. At what angle of the string from the wall at a stable equilibrium Homework Equations Gauss' Law Integral (E * A) = Q/\[Epsilon]...

so simply .5 in the upwards direction

Homework Statement A bird has gathered electrical charge of .0001C by rubbing against another bird(I have no idea why the bird is doing this but...) and it is flying to a certain point where there is a thunderstorm brewing and a vertical electrical field of 5000N/C. What is the electrical...
