ok I think I might have gotten the first one... I just figured if it's got to be deflected east then there must be some force to the east so by the equation F=qv X B for F to be in the +x direction or East, and with v being in the - y direction and B also in the -y direction, then + = q (-)(-)...

Hey I tried posting this in another thread but no one was answering and I'm really quite stuck...
ok here's my problem(s)... I think the first one I'm missing something...
it says:
A particle initially moving south in a vertically downward magnetic field is deflected toward the east...

it says:
A particle initially moving south in a vertically downward magnetic field is deflected toward the east. What is the sign of the charge on the particle? Explain your answer with a diagram.
So the way I...
dangerous balloons?
Thanks just the same :) I've finished yet another physics assignment! Well except for part c of one of them... why isn't a balloon charged with 1200V potential difference (relative to me) dangerous? I know that it isn't, but I don't think they're looking for "bc it's a...
It seems like this should be really easy but I've been stuck for awhile...
A small particle has charge -5.00 uC and mass 2.00E-4 kg. It moves from point a, where the electric potential is Va=+200V, to point b, where the electric potential is Vb=+800V. The electric force is the only force...
hey I think I got part a of the second one...I'm so dumb all I had to do was make the distances be the radii of the gaussian surface right? and then I got the charge based on the first length, then I got the second E with the charge...I really think I got it! Awesome :) now on to cylinders...
So even though there's a charged sphere like 3 cm away it doesn't affect the flux on the cube all because it's empty. So I had to kinda put a Gaussian surface around the box, not the sphere... That's good to know...
and for the Second one the work I did already was wrong too huh? I'll have...
I am using the University Physics with Modern Physics 11th Edition and I tried to get onto masteringphysics.com today but I don't have a course code or something so I'm still working on that one...it's not required for the class so it's no big I just needed help with Gauss' Law tonight so I was...
Ok here's what I tried for 1 I went with Flux=integral of E da and got as far as the flux was 2.3 x 10^5 for the sphere, then I didn't even know why I got the flux at all... I'll look at Gauss' Law again I guess..
Other question, what is the value of epsilon naught? Because I know that...
I need some guidance if anyone can help me!
1. A small cube of volume 8.0 cm^3 is .30 cm from a metal sphere that has charge 2.00uC. If the cube is empty, what is the total flux through it?
I tried finding the flux of the sphere as if it was a point charge but I don't know where to go...
