An electron starts from rest near a negatively charged metal plate, and is accelerated toward a positive plate through a potential difference of 900 volts. The electron passes through a hole in the positive plate, into a region where the electric field is negligible. Take the position of the electron at the instant shown in the diagram to be the origin, with the  and  axes as shown, and the  axis out of the page toward you. Find all three components of the magnetic field at location A<0.005,-0.004,0> m due to the moving electron.

The figure below shows the end view of four long parallel wires (labeled 1 through 4) each with a current of 8.40 A arranged in a square with sides of length 0.380 m. The current direction is out of the page for wires 1 and 2 and into the page for wires 3 and 4. Write a vector expression for the magnetic field at the point P which is at the center of the square.

An electron is traveling with a constan velocity vo in the presence of a uniform electric mg field E-Ek, where E- e (Here, m denotes the mass of the electron and e denotes its charge. g denotes the acceleration due to gravity). Gravity acts in the -Z direction. At t=0, when the electron is at the origin, a uniform magnetic field BB+BJ is switched on. Here. B, and B, are fixed positive BB. The coordinates of the point where the electron intersects the X-Y plane constants and B for the first time after t=0 are given by: 2amy B Zamy BB e (A) (C) 2 e B 2AMY, B B (B) (D) 2amv, B.B. e B 2rum BB B Lamy B.B B 2am B B

An electron with velocity v = vê enters a region where there is a uniform electric field E = E,î . If the electron is to continue undeflected from its initial trajectory, what magnetic field (magnitude and direction) is necessary? Write your answer in terms of Eo, vo and unit vector.

An electron moves in a uniform circular motion under the action of an external magnetic field. -19 Consider the charge of the electron 9 = -1.6 × 10- v = 2.8 X 107 [C], the speed of the electron B = 2.1 x 10-³ [m/s] and the magnitude of the external magnetic field [T]. Calculate the radius R of the circle formed by the electron during its displacement. Write your answer in centimeters and round to the first decimal.

why does the colour of sunset vary from day to day?

A single charged ion of oxygen-16 (with a mass of 2.68×10-26 kg), moves at constant velocity through a velocity selector with the electric field E= 4x104 N/C. When the electric field is turned off, the ion travels in a circular path of radius 1.33 mm. Determine the magnetic field in the selector (in T). Enter your answer with two digits after the decimal point.
