So then after I get the two forces do I just add them to get the net force? And after I have the net force how do I go about the rest of the problem?

so then the mass of the ions is irrelevent? because my teacher did say as a hint to remember that ion charges are multiples of the charge on an electron, and their masses in atomic weights are multiples of the mass of a proton

Ok so then my cable length would be equal to my wavelength and the distance between nodes on the 7th harmonic would be 1/7 of the wavelength?

Half of the wavelength would be the length of the cable correct?

I guess what I am trying to figure out is what the Q1 and Q2 are in the force formula?

Do I need to convert my 7.0 MHz to Hz and if so what is the conversion factor? Also, how do I know how many wavelengths are on a wire? the above formula gives me the wavelength but then I am not sure how many wavelengths are on the wire.

should my Q1 and my Q2 have the same number because they both have a negative charge?

so does that mean my force would be = 5.77 X 10^-11

velocity=(frequency)(wavelength)?

A sphere with a charge of 5.0 x 10^-6 C is placed one fifth of the distance between two negatively charged spheres, as measured from the left. The sphere to the left has a charge of -3.0 x 10^-6 C and the sphere to the right has a charge of -6.0 x 10^-6 C. A distance of 10.0cm separates the...

Please help with the following problem: A proton is placed between two oppositely charged plates, with a potential difference of 20.0 volts. if the distnace between the plates is 0.20 cm, calculate the following: a. The ratio of the acceleration of the proton to an electron between the...

I have yet another problem that I need help with. An elctromagnetic wave with a frequency of 7.0 MHz forms a standing wave pattern on a transmission cable. The velocity of the wave in the cable is 0.95 of the speed of light in a vacuum. the length of the cable is such that the third harmonic...

A charged ion with a molecular weight equal to 75.0 proton masses and a charge of 1 proton is placed into a magnetic field given by the vector 3i + 12j + 7k. It is moving with a velocity given by the vector -7.0k. wat is the net force and what is the net acceleration produced? What is the net...

An iodine (-1) and a chloride ion (-1) interact in a vaccum. a. What is the force which each exerts on the other from a distance of 2.0 x 10^-9 m? b. What is the eletric field that the iodine ion experiences from the chloride ion? toward which ion does the electrical field vector point...

So then would my answer be 538.87 liters or 53.87 buckets of water?
