Circular Mtion and Magnetic field Question ...This is really giving me a hard time!
1) In the 'Wall of Death' motorcycle stunt,the rider gradually rides higher around a curving wall of a circular arena until he is traveling around a vertical wall.
a) show the forces acting on a rider and the bike and explain how their weight is supported.
b)Before reaching the vertical wall ,the rider travels more slowly round the sloping section of the arena.What additional force provides support at this stage?
2)A magnetic field of 0.5 T and an electric field of 5000V/m are arranged to produce opposing forces on an elcetron.calculate the speed at which electron is travel in a straight line through these fields.
I haven't got a clue how to do the above questions.Any hints will highly be appriciated.
