## Homework Statement

The total electric flux from a cubical box 34.0 cm on a side is 1.29 x 103 N·m2/C. What charge is enclosed by the box?

----and----

Three charged particles are placed at the corners of an equilateral triangle of side

*d*= 1.00 m (Fig. 16-53). The charges are

*Q*1 = +4.0 µC,

*Q*2 = -6.0µC, and

*Q*3 = -6.0 µC. Calculate the magnitude and direction of the net force on each due to the other two.

Figure 16-53

Force on

*Q*3: N at ° counterclockwise from +

## Homework Equations

Gauss' Law (I think)(I don't know how to type those symbols out sooo)

----and----

I'm not really sure on this one. I've tried setting it up F=(k)(d^2/|Q(#)Q(#)) to find the magnitude but that isn't working (or at least my numbers are weird for it)

## The Attempt at a Solution

I tried to multiply (1.29

----and----

See above
