Net Electric Field Homework Solution

AI Thread Summary
The discussion focuses on solving a homework problem related to calculating the net electric field using the equation E=kq/r². The user simplifies the problem by decoupling the x and y components, concluding that there is no net electric field in the x direction. For the y component, the user attempts to calculate Ey using the given values and geometry, but initially forgets to square the distance in their calculations. After correcting this oversight, the user arrives at a value of 3295.12 N/C for the electric field. The conversation emphasizes the importance of careful calculations in physics problems.

Homework Equations


E=kq/r2

The Attempt at a Solution


So i decided to do decouple the x and y values to make it simpler
For Ex It became apparent through the geometry and charges that there would be no net field in the x direction

For Ey:
k/r2* (-absq1+absq2+absq3-absq4)sinθ
= 8.99E9/(.5*√2*.067)*(-6.31E-9+18.6E-9+18.6E-9-631E-6)sin(π/4)
=3295.12 N/C

Nevermind, forgot to square the distance.
 

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 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanging mass'

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...
