Workdone between 2 charges2/27/2023 The energy acquired by a charged particle accelerated by an electronic field in a vacuum depends only on its charge and the p.d. If the electron moves in a circle of radius r, the force towards the centre inmv 2r (centripetal force), and it is provided by the electrical force of attraction When the electron is in motion, its kinetic energy will be ½ mv 2. I e V = 1.6 x 10 -19 x 1 = 1.6 x 10 -19J The energy acquired by a charged particle accelerated by an electronic field in a vacuum depends only on its charge and the p.d. The electron volt is the quantity of energy gained by an electron in accelerating through a potential difference of one volt. Work done on the charge, W = Q (V 1 – V 2) ELECTRON VOLT (eV) If a charge Q is moved from a point at a potential V 1 to another at a potential V 2, the potential difference (V 1 – V 2) is the work done by the field. The potential difference between any two points in an electric field is the work done is taking a unit positive charge from one point to another in the field. I unit is (N/C), mathematically.Į= Electric field intensity (NC-1), F = Force, q = charge. The electric field intensity, E, at any point in an electric field is the force experienced by a unit positive test charge at that point. Find the resultant force acting on 15C charge.
