The electron gun in a television tube uses a uniform electric field to accelerate electrons from rest to 4.4x107 m/s in a distance of 1.3 cm What is the electric field strength?
The electron gun in a television tube uses a uniform electric field to accelerate electrons from rest to 4.9×10^7 m/s in a distance of 1.4 cm What is the electric field strength? I have that E=f/q, I'm not sure how to incorporate velocity and distance into this formula to find E.

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 cm the electrons are accelerated to a speed of 1.62x107 m/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 6.42x103 N/C perpendicular to...

Electrons inside a particular X-ray tube travel d-5.5 cm. The electrons begin at rest and accelerate to a speed that is,f=1/12 of the speed of light. Calculate the strength of the constant electric field that caused this acceleration. PAPER SOLUTION ▼ INTERPRET ldentify all of the true statements. A. A proton would have the same acceleration because it has the same charge as an electron. B. A constant electric field will cause an electron to accelerate. C. A proton would...
The electron gun in a TV picture tube accelerates electrons between two parallel plates 1.20 cm apart with a 25.0 kV potential difference between them. The electrons enter through a small hole in the negative plate, accelerate, and then exit through a small hole in the positive plate. Assume that the holes are small enough not to affect the electric field or the potential. (a) What is the electric field between the plates? (b) What is the exit speed of...
