An electron starts from rest near a negatively charged metal plate, and is accelerated towards a positive plate through a potential difference of 1320 volts. the electron passes through a hole in the positive plate into a region where the electric field is negligible. calculate the magnetic field at the location a, a distance of 0.008 meters from the electron, due to the moving electron.

A33.1 g copper object is launched from a 1.5 m 30Ā° steel incline positioned on the floor by being pulled up a string attached to a 50.0 g mass suspended vertically over a pulley. the object is projected towards a glass table where it lands when it is at the point along its trajectory with the lowest speed. it comes to a halt when it clears the opposite edge of the table. it then falls and lands on 9 physics texts each 5 cm thick that are stacked on the floor on the opposite side of the table. assume that the table does not have a ledge and the rectangular object experiences 0.05 n of air resistance as it falls towards the books. how far and how long did the object travel and how fast does it hit the books. assume that at the moment the copper object leaves the incline, the massless string and ideal pulley break off
