Did I Misunderstand the Direction of Force on the Electron in an Electric Field?

AI Thread Summary
The discussion centers on the confusion regarding the direction of force acting on an electron in an electric field. The electric field is directed upwards, leading to the conclusion that the force on the negatively charged electron acts downwards. Participants verify calculations related to the electron's final velocity, with one expressing uncertainty about the correct value. Despite some miscommunication about numerical results, the overall understanding of force direction and its implications for acceleration remains clear. The thread emphasizes the importance of correctly interpreting the relationship between electric fields and charged particles.

The Attempt at a Solution



I think my main source of confusion is this problem is how the force is acting on the electron.

The picture shows that the electric field is pointing straight up, but since its acting on an electron (negative charge) the force will be in the opposite direction correct? (i.e. straight down)

If this is the case the acceleration the electron experiences is a vertical acceleration downwards.

Anyways, here's my attempt at the problem,

Check your calculation for Vyfinal, A is downwards and therefore negative

Wait, I'm getting the same number, 0.83m/s ?
 
i thought its 083! sorry,

everything else seems fine

what's the correct answer?

I don't know it's not given. I was wanting to check that as well.
 
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 .
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...
