1. ### Uniformly Charged Sheet

thank you, Henxan! The sheet does have two sides and therefore i got the correct answer for 1 :P However, do you know how am i supposed to do the other two parts of the problem? If you do, would you kindly help me. :)
2. ### Uniformly Charged Sheet

Yes, that is how i calculated the area
3. ### Uniformly Charged Sheet

Homework Statement A charge of 4.1 nC is placed uniformly on a square sheet of nonconducting material, with side 19.0 cm, that lies in a horizontal plane. 1. What is the magnitude of the electric field just above the center of the sheet? The same charge is placed on a horizontal square...

thank you so much after reading your reply i found out that i made a foolish calculation mistake. The correct answer should be x = (sinø_2 L) / (tan ø_1 cos ø_2 + sinø_2), i was right, but i simplified it incorrectly, now i can't figure out how to simplify this is expression in terms of tangents :(

I guess i should write sum force x, but isn't the equation itself correct? for the second equation, i setted the torque around center of mass to be 0; then calculated for x which is the distance from the left end to the center of mass. thank you for replying
