Homework Statement
A charge of -4.1 microC is located at the origin and a charge of -2.98microC is located along the y-axis at 2.11519 m.
The value of the Coulomb constant is 8.99x10^0.
At what point along the y-axis is the electric field zero? Answer in units of meters.

Hello,
I was wondering if we had a square with side length a and charges q. What would be the electric field at a corner? I can work this out by breaking stuff into components but I wondered if there was an easier way using very basic linear algebra. What about a cube? In other words are...
Identical isolated conducting spheres 1 and 2 have equal charges and are separated by a distance that is large compared with their diameters. The magnitude of the electrostatic force acting on sphere 2 due to sphere 1 is F = 8.9 N. Suppose now that a third identical sphere 3, having an...
The problem states: Calculate the number of coulombs of positive charge in 250 cm3 of (neutral) water. (Hint: A hydrogen atom contains one proton and an oxygen atom contains eight protons.)
Ok, first I converted to moles. Using the density of water.
250mL * \frac{1g}{1mL} * \frac{1 mole...
Two charged particles, with charges q_1=q and q_2=4q, are located a distance d apart on the x axis. A third charged particle, with charge q_3=q, is placed on the x-axis such that the magnitude of the force that charge 1 exerts on charge 3 is equal to the force that charge 2 exerts on charge 3...
We are dealing with Coulombs law or w/e in Physics right now AND I DONT GET IT lol In my homework. it gives numbers like +6.0 (weird u symbol)C and i jus don't understand how to find the magnitude and direction of everything..
Im a junior in Physics..so someone of higher...
Coulombs law, and 3 "point particles" (vector question)
The drawing shows three point charges fixed in place. The charge at the coordinate origin has a value of q1=+8.00 mC; the other two have identical magnitudes, but opposite signs: q2=–5.00 mC and q3=+5.00 mC. (a) Determine the net force...

*graphic* is kind of distorted.
So the coordinates of the charges are:
q1 = (0,1)
q2 = (2,0)
q3 = (2,2)
given:
q1 = 2.5 x 10^-5 C
q2 = 2.0 x 10^-5 C
q3 = ?
Problem:
If the force on q1 points in the...
Two charges, q1 and q2, are held a fixed distance d apart. a. Find the strength of the electric force that acts on q1. Assume that q1=q2=21.3 micro COulombs and d=1.52 m. b. A third charge q3=21.3 micro COulombs is brought in and placed as shown. Find the stregnth of the electric force on q1...
Likewise, this similar problem also has me stumped
A charge of 7.00 mC is placed at each corner of a square 0.80 m on a side. Determine the magnitude of the force on each charge.
Any help would be greatly appreciated!
All right i have a simple problem but i just want to verify my results, so any help would be greatly appreciated. The problem is as follows:
7.1* 10^12 electrons are added to a body that already has a negative charge of 0.2uC(the u is micro 10^-6). Calculate the final charge on this body...
Hi,
I'm seeking help with a couple of problems involving electrostatics.
Q1)Calculate the electric field at the centre of a square 0.1m on a side if one corner is occupied by a charge 0.2micro C, and the other three corners are occupied by the charge of -0.9micro C
Q2) A positive test...
Hi everyone its my first time here, read the forums greatly though and have been a help in understanding but now I am completely lost on this problem: Calculate the number of coulombs of positive charge in 250 cm^3 of (neutral) water (about a glass full). So far I tried converting the volume to...
