How Does Coulomb's Law Determine Force in a Charged Square Configuration?

AI Thread Summary
Coulomb's Law is applied to calculate the electric force on charges located at the corners of a square configuration. Each corner charge of -1.0x10^-6 C experiences a net force of 22.5 N due to interactions with the other three charges. The calculation utilizes the formula Fe = kq1q2/r^2, where k is the Coulomb's constant. It's essential to consider the direction of the forces by setting up coordinate axes and treating the forces as vectors. This approach allows for a comprehensive understanding of the force dynamics in the charged square configuration.

Homework Statement


A square with side lengths 2.0 cm has a charge of -1.0x10^-6 at every corner. What is the magnitude and direction of electric force on each charge?


Homework Equations


Fe=kq1q2/r^2


The Attempt at a Solution


FeNet=kq1q2/r^2
=(9x10^9)(-1.0x10^-6)^2/(0.002)^2
=22.5 N

You will need to take into account the direction of the force. Set up some coordinate axes and treat the force from each of the 3 other charges on one charge as a vector. Once you've found one the others should be obvious.
 

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'A bead-mass oscillatory system problem'

I can't figure out how to find the velocity of the particle at 37 degrees. Basically the bead moves with velocity towards right let's call it v1. The particle moves with some velocity v2. In frame of the bead, the particle is performing circular motion. So v of particle wrt bead would be perpendicular to the string. But how would I find the velocity of particle in ground frame? I tried using vectors to figure it out and the angle is coming out to be extremely long. One equation is by work...
