Electric Electric field Field Net

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 E_x It became apparent through the geometry and charges that there would be no net field in the x direction

For E_y:
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 '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 'I've come across another fluid pressure problem I don't understand'

Neglect gravity other than that of water; neglect friction. F1=ρgsh=1000*10*1*(1+4)=50000 N; F1=ρgsh=1000*10*0.1*4=4000 N; F3=50000-4000=46000 N?

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...
