AI Thread Summary
The discussion focuses on calculating the electric field inside a charged sphere with a radius of 10 cm and a charge of 0.4 µC. The electric field just outside the sphere is determined to be 360,000 V/m. However, the main question is how to find the electric field within the sphere. It is noted that the electric field inside a uniformly charged sphere is zero. The thread highlights the need for clarification on applying the relevant equations for electric fields in different regions of a charged sphere.

Homework Statement



what is the magnitude and direction of teh electric field just inside the sphere?
givens: radius=10cm charge=.4uC

Homework Equations



E=kq/r^2

The Attempt at a Solution


i found that the electric field just outside the sphere is 360000vm^-1
i just don't know how to find the field on the inside of the sphere

Thread 'Voltmeter readings for this circuit with switches'

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...
