To the right. I know how to use the right hand rule, but in this situation I am confused with the loop inside the solenoid. The magnetic field inside the solenoid points to the right, but how does that affects the current inside the loop? Would the current at location A point outside the paper?

Thank you for answering! I was not really thinking about the acceleration, I thought it would have the same direction as the velocity of the particle! But would it be perpendicular to its motion? Then the acceleration would be parallel to the force exerted by the magnetic field, so the answers...

Homework Statement Consider a charged particle moving with velocity v through a magnetic field B. Answer True or False. 1) The magnetic field B is always perpendicular to the acceleration a of the particle. 2) The magnetic force F is always perpendicular to the acceleration a of the...

https://www.dropbox.com/s/gvml20bk7435zoa/a.gif I need to calculate the equivalent capacitance of this circuit, but I cannot tell which of the capacitors are in series or in parallel. Can someone explain to me how can we figure this out?
