Hello, I'm stuck (again) on a physics problem.
The problem:
Early in 1981 the Francis Bitter National Magnet Laboratory at M.I.T. commenced operation of a 3.3 cm diameter cylindrical magnet, which produces a 30 T field, then the world's largest steady-state field. The field magnitude can...
Thanks, confirming that I was going in the right direction was all I needed. I eventually did get the answer, but with some difficultly thanks to my poor algebra skills. :)
I've been stuck on this problem for awhile now..
At what distance along the central axis of a ring of radius R and uniform charge is the magnitude of the electric field due to the ring's charge maximum?
Now, I know that the equation for this problem is E = [k|qz|] / [(z^2+R^2)^3/2], which...
Thank you for the help! Turns out it was atmospheric pressure. You have to add it to the pressure of the water and then multiply by area to get force.
I should read more carefully. :)
Hello everyone, newbie here.. sorry if I posted this in the wrong place.
We just went over fluids today. And I can’t seem to solve a problem that has to do with force due to pressure. The problem is: An open U shaped container is filled with water to the top. What is the force due to the...
