What is the equation for uniform electric fields?

AI Thread Summary
The discussion revolves around understanding the equation for uniform electric fields, specifically in the context of a charged object experiencing an electric force. The relevant equation is F = Eq, where F is the force, E is the electric field strength, and q is the charge. The problem involves a charge of -3.6μC and a mass of 0.012kg, with the electric force balancing its weight, indicating the direction of the electric field is upward. If the charge is doubled while keeping the mass constant, the acceleration can be determined using the same principles. The focus is on grasping the concepts of direction and magnitude of electric fields in a non-calculus context.

Homework Statement



An object with a charge of -3.6μC and a mass of .012KG experiences an upward electric force, due to a uniform electric field, equal in magnitude to its weight. Find the direction and magn. of the field, and if the charge is doubled while its mass remains the same, find the direction and magn. of its acceleration.I really have no idea what this is. Is there an equation for uniform electric fields? I don't really even understand direction or magnitude of fields in this problem.

Oh and sorry it's a non-calculus course.

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...

Thread 'Struggling to make relation between elastic force and height'

Hello guys this is what I tried so far. I used the UTS to calculate the force it needs when the rope tears. My idea was to make a relationship/ function that would give me the force depending on height. Yeah i couldnt find a way to solve it. I also thought about how I could use hooks law (how it was given to me in my script) with the thought of instead of having two part of a rope id have one singular rope from the middle to the top where I could find the difference in height. But the...
