There is a uniform downward electric field below a thundercloud. The magnitude of this electric field is E=28.3 kN/C. Useful constants: Mass of an electron: 9.11×10-31 kg Charge on an electron: -1.60×10-19 C What is the magnitude of the acceleration on an electron in this field?
A spatially uniform magnetic field B exists within a cylindrical volume of radius R, pointing into the page. at the rate of 10.0m. (i) Find the initial acceleration of a proton released at a point a directly below the center of the cylinder, at a radial distance of 5.00cm. The magnitude of this field is decreasing (ii) Now find the acceleration of an electron released at the same point. both parts. (HINT: Use your knowledge of Faraday's Law to first...

Problem 2 (a)What is the magnitude of an electron's acceleration in a uniform electric field of magnitude 1.87 x 106 N/C? (b)How long would the electron take, starting from rest, to attain 1/15-th the speed of light? (c)How far would it travel in that time?
A vertical electric field of magnitude 2.50 kN/C exists above the Earth’s surface on a day when a thunderstorm is brewing. A car with a rectangular size of approximately 6.20 m by 3.40 m is traveling along a roadway sloping downward at 12.0˚. Determine the electric flux through the bottom of the car.
A scanning electron microscope uses a uniform 15.0-kN/C electric field to accelerate electrons horizontally toward the subject to be imaged. After travelling 5.0 cmthe electrons are accelerated to a speed of 1.62x107m/s. The next step is to deflect the electrons so that they can scan across the sample—hence the scanning electron microscope. To accomplish this, the electrons are directed between a pair of oppositely charged parallel plates, which produce a uniform electric field of 6.42x103N/C perpendicular to the electron beam....
