Electric Field Strength on Cube Faces

AI Thread Summary
The discussion focuses on calculating the electric field strength and direction on a specific face of a cube influenced by varying electric fields. The participant expresses confusion about how to approach the problem, particularly regarding the directionality of the electric field. Another contributor advises determining the sign of the flux based on whether the electric field arrows point inward or outward, with outward being positive and inward negative. The importance of considering the perpendicular direction of the electric field to the cube's faces is emphasized. Clarification on these points is essential for solving the problem accurately.

Homework Statement


lectric fields of varying magnitudes are directed either inward or outward at right angles on the faces of a cube, as shown in the figure.

What is the strength and direction of the field on the face F? (The cube does not contain any charges. Take EA = 13 N/C, EB = 26N/C, ED = 22 N/C, and EE = 21 N/C.)

The Attempt at a Solution



I am not sure how to do this problem any hints? i you add up the flux but it doesn't have a direction in which the electric field is going so i am confused.

Look at the picture to determine the sign of the flux. for arrows pointing outward take the flux to be positive, and inward to be negative. the direction is perpendicular to each face.
 
arg i didn't look at the 10 which was C
thanks !
 

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...
