II. A stationary proton is moved from point A, where the potential is 450V, to point B, where the potential is 125V. Answer format: +1.2x10^-3 [unit] (make sure to put +/- in the number and the exponent of the notation) (If answer is zero, put 0) (Use one decimal place for final answer) TAKE NOTE: When solving, use as many decimal places as you can in computing for the values. Your answers below should not be used in calculating for other values because it is already rounded off and might affect your answer. How much work is done by the electric force? What is its speed at point B? What is the electric potential energy at point A? What is the electric potential energy at point B?

Please solve and answer the question correctly please. Also be sure to give the correct units. Thank you!!
4. Having found the voltage difference from knowing the electric field, we can also do the inverse, find the electric field if we know the voltage as a function of position. Since the inverse of integration is differentiation, we have: av Ey ây' The partial derivative OV/Ox means that to take the derivative with respect to x while treating y and z as constant. The electric potential in a region of space is given by Ex = What is the electric field in this region? av Əx' 2 5y V (x, y, z) = V. ((-)² – 57) av əz

: The first two charges are (-5 MC) and the second is (12 MC). Calculate the point for making the electric field equal to zero if you know that the distance between the two charges is 2.00 m. Q2: A charge uniformly distributed through an insulating sphere of radius R with a volumetric density (p (C / m3). Find the electric potential at points far from the center of the sphere. When: -1 - (r> R) b - (r <R)
Current Attempt in Progress - Your answer is partially correct. The figure shows a ring of outer radius R = 25.0 cm, inner radius r = 0.290R, and uniform surface charge density 0 = 2.10 pC/m². With V = 0 at infinity, find the electric potential at point P on the central axis of the ring, at distance z = 1.10R from the center of the ring. Number i 1.186E-3 Units V O

Two large charged plates of charge density ±18µC/m² face each other at a separation of 7 mm. Choose coordinate axes so that both plates are parallel to the xy plane, with the negatively charged plate located at z = 0 and the positively charged plate at z = +7 mm. Define potential so that potential at z = 0 is zero (V(z = 0) = 0). Hint a. Find the electric potential at following values of z: o potential at z = -7 mm: V(z = -7 mm) = o potential at z = +1 mm: V(z = +1 mm): = o potential at z = +7 mm: V(z = +7 mm) = = o potential at z = +9.2 mm: V(z = +9.2 mm) = V. V. V. V. b. An electron is released from rest at the negative plate. With what speed will it strike the positive plate? The electron will strike the positive plate with speed of m/s.
