Get started for freeAn electron at point in figure has a speed . Find (a) the magnetic field that will cause the electron to follow the semicircular path from to and (b) The time required for the electron to move from
An electron moves at through a regionin which there is a magnetic field of unspecified direction and magnitude . (a) What are the largest and smallest possible magnitudes of the acceleration of the electron due to the magnetic field? (b) If the actual acceleration of the electron is one-fourth of the largest magnitude in part (a), what is the angle
between the electron velocity and the magnetic field?
A 140-g ball containing excess electrons is dropped into a 110-m vertical shaft. At the bottom of the shaft, the ball suddenly enters a uniform horizontal magnetic field that has magnitude 0.300 T and direction from east to west. If air resistance is negligibly small, find the magnitude ond direction of the force that this magnetic field exerts on the ball just as it enters the field.
A 1.50- F capacitor is charging through a 12.0-Ω resistor using a 10.0-V battery. What will be the current when the capacitor has acquiredof its maximum charge? Will it beof the maximum current?
