Thanks! I will review that material and if I have more trouble, I will let you know. Thanks so much for your time!

I was thinking positive repels positive and maybe it would push the field away. Now I am thinking they will both go towards point c so I have to figure both going in the direction towards point C.

They are 60 degrees. Coulomb's Law, the forces will be opposite?

Thanks!

So, would I take the force that is listed in the problem and add the force of gravity on the object that I solve for then take the cumulative of the two ans use that as the F in the a= F/m formula?

hmmm. Gravity? :) Wow! I think the lightbulb just came one.. :)

I thought maybe that the direction from B would be towards C just like the direction from A is to C. I am not sure if I am looking at that right though. Wouldn't the magnitude be the same??

I am not sure. I thought so because I followed the example in the book.

Homework Statement Points A, B, and C are at the vertices of an equilateral triangle. A certain positive charge q placed at A produces an electric field of magnitude 145 N/C at C. Suppose a second, identical charge is placed at B. What is the magnitude of the new electric field at C...

Homework Statement During a thunderstorm the electric field at a certain point in the Earth's atmosphere is 1.07e5 N/C, directed upward. Find the acceleration of a small piece of ice of mass 1.09e-4 g, carrying a charge of 1.08e-11 C. Homework Equations F= (q')(E) a= F/mass...

Thank you sooo much! That helped a lot!

Homework Statement I was given this problem in class and I am unable to figure it out: A copper wire 90.0 cm long and 1.00 mm in diameter has a mass of 6.35 grams. (a) find the number of electrons in the wire ( Copper has an atomic number of 29; that is there are 29 protons in the...
