I NEED THIS ANSWERED BEFORE MIDNIGHT PST! I WILL RATELIFESAVER!

A very thin glass rod 4 meters long is rubbed all over with a silkcloth. It gains a uniformly distributed charge 1.6X10^–6 C. Twosmall spherical rubber balloons of radius 1.2 cm are rubbed allover with wool. They each gain a uniformly distributed charge of-8X10^–8 C. The balloons are near the midpoint of the glass rod,with their centers 3 cm from the rod. The balloons are 2 cm apart(4.4 cm between centers).




(a) Find the net electric field at the location marked by the X,0.6 cm to the right of the center of the left balloon. Things tothink about: Which objects make nonzero contributions to E field atthis location? What are the correct distances from sources to theobservation location? What is the direction of E field due to therod? (The drawing is not to scale; read the problem statementcarefully. Assume the +x axis is to the right, the +y axis is up,and the +z axis is out.)

E = ________ N/C

(b) What approximations did you make, if any? Which apply(1-4)?
1. Neglect polarization of balloons.
2. Use approximate formula for electric field of a chargedspherical shell.
3. Neglect polarization of rod.
4. Assume distance to observation location is small compared tolength of rod.

(c) Next a proton is placed at that same location (marked by thex). What is the force acting on the proton?

F = ________ N
Note: in parts (a) and (c) there should be an arrow over the"E" and the "F" but the custom equation function would not workproperly.
