The electric field points due east and has a magnitude of 4.3 105 N/C. The mass of the electron is 9.11 10-31 kg and that of the proton is 1.67 10-27 kg. Both the proton and electron have charge magnitudes of 1.60 10-19 C. (d) What is the algebraic expression for the magnitude a of the acceleration that a charge experiences when placed in an electric field? Express your answer in terms of the magnitude |q| and mass m of the charge, and the magnitude E of the electric field. (e) Determine the magnitude ap of the acceleration of the proton. Number Unit ap = (f) Determine the magnitude ae of the acceleration of the electron.
A moving particle encounters an external electric field that decreases its kinetic energy from 9800 eV to 8350 eV as the particle moves from position A to position B. The electric potential at A is -43.0 V, and that at B is +23.0 V. Determine the ..
