An electron is projected with an initial speed 1.90x106 m/s into the uniform field between the parallel plates in the figure (Figure 1). Assume that the field between the plates is uniform and directed vertically downward, and that the field outside the plates is zero. The electron enters the field at a Part A point midway between the plates. If the electron just misses the upper plate as it emerges from the field, find the speed of the electron as it emerges from the field?

Cathode ray tubes (CRTs) used in old-style televisions have been replaced by modern LCD and LED screens. Part of the CRT included a set of accelerating plates separated by a distance of about 1.36 cm. If the potential difference across the plates was 27.0 kV, find the magnitude of the electric field (in V/m) in the region between the plates.

The image shows a coaxial cable (two nested cylinders) of length l, inner radius a and outer radius b. Note that l >> a and l >> b. The inner cylinder is charged to +Q and the outer cylinder is charged to −Q. a) Use Gauss’s Law to calculate the electric field E at r < a, a < r < b, and r > b.  b) Calculate the electric potential difference between a and b that is ∆Vab

A particle with mass m = 4.50 mg and charge Q = 75.0 μC enters a region of space where there exists an electric field between two vertically arranged parallel conducting plates, which carry opposite charges - these charges establish the field between the plates. The particle enters via a hole in the positively charged plate and after a short time leaves the region via a hole in the negatively charged plate as shown in Figure 2. The field between the plates is 3, 150 ÎN C¹. If the plates are 15.0 cm apart, and the particle enters with a speed of 5.70 x 10²m s¹, determine the speed of the particle as it exits the region between the plates. V Figure 2:

A pair of charged conducting plates produces a uniform field of 20,000 N/C, directed to the right, between the plates. The separation of the plates is 50 mm. A proton is projected from plate A, directly toward plate B, with an initial speed of vo = 1.0 × 105 m/s. What is the speed of the proton as it strikes plate B? Vo Provide the solution:___ x105 m/s + +

A parallel-plate capacitor has a charge Q and plate separation d, as shown below. We assume that the size of plates is much larger than the separation d. Each particle is initially at rest and then released, allowing it to accelerate.  Assuming each particle has the same mass, rank the speeds of the particles when they impact the left plate. 1.
