- Homework Statement
- two parallel wires. The distance between the wires is d from each other and they are connected by a capacitor with the capacitance C. The constant magnetic field B is applied and is perpendicular to the plane of the wires. We put a metallic bar across the parallel wires and start pulling it with force F parallel to the wires. What is the acceleration of the bar?
- Relevant Equations
- I also attached my work to a file so it can be readable. I also did it here below:
I so far did C=Q/V,
I=dQ/dt,
I=c*dV/dt
F=ma, F=-IlB. I set these equations equal to each other:
ma=-IlB, In the next step I substituted c*dV/dt for I and got:
m*dv/dt=-(cdVlb)/dt
then, I substituted a into dv/dt and solved for a and then for final answer:
a=-(cvlb)/(mt)
I am not sure if this is correct or if I am on the right path.
I need help with the problem above
