A uniform electric field E= 3500 V/m exists within a certain region. What volume of space contains an energy equal to 3.00 x 109 J? Express your answer i) in cubic meters, and ii) in liters?

Two conductive plates are oriented such that they are exactly parallel to one another and are exactly 6.00 mm apart. Charge is distributed between the two plates and a potential difference of AV = 323 V is measured between the two plates. What is the magnitude of the electric field between the two plates? Hint: In such a situation, the electric field is extremely uniform.

A From Equation 25.6, we have the following. AV = -Ed = -(7.2 × 104 v/m)(0.60 m) = B V From Equation 25.3, we have the following. AU = qAV = eAV = (1.6 x 10-19 C)(AV) | The negative sign means that the potential energy of the system decreases as the proton moves in the direction of the electric field. This decrease is consistent with the conservation of energy in an isolated system: as the proton accelerates in the direction of the field, it gains kinetic energy and at the same time the system loses electric potential energy. The increase in kinetic energy of a charged particle in an electric field is exploited in many devices, including electron guns for TV picture tubes and particle accelerators for research in particle physics. You can predict and observe the speed of the proton as it arrives at the negative plate for random values of the electric field using this Interactive Example. Hints: Getting Started | I'm Stuck Exercise 25.2 For the previous example, apply the principle of…

A cylindrical capacitor consists of a solid conducting cylinder with a radius of 0.260 cm and a coaxial conducting tube around it. There is air between the conductors and the length of the cylinder is 12.5 cm. If the capacity of the device is 38.5 pF; Part A: Calculate the inner radius of the outer tube.(r=?) Part B: What is the stored charge per unit length, λ when the shaver is loaded with 130 V? (λ=?)
