Are you sure the solenoid doesn't create a magnetic field?
2. ### Alright PF logged me out and erased all my work

Give me a minute, I'll solve this. EDIT: Before I do anything. Are you sure that your expression here is correct?: I_2 B_1 = I_1 B_2 When I expand from: |F_{12}| = |-F_{21}| I get: I_1 l_1 B_1 = I_2 l_2 B_2 Where the lengths of the wires can cancel since they are the...
3. ### Object Slowing on a Horizontal Surface after Rolling down an Inclined Plane

Yeah, apparently I'm fking retarded. I forgot that Fnet = whatever the Ff is. I thought the object would be carrying some Fapp with it as it still had speed from coming down the inclined plane. I solved the problem. Thanks for the help. :)
4. ### Object Slowing on a Horizontal Surface after Rolling down an Inclined Plane

Homework Statement Block A starts from rest and slides 8m down a frictionless 30 degree angled inclined plane. It then crosses a 4m horizontal surface where the coefficient of kinetic friction is 0.2. What is the velocity of Block A after it has finished crossing the horizontal surface...
