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 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
