Question an electron is near a positive ion of charge 9e, Ask an Expert

Academics

Question: An electron is near a positive ion of charge +9e and a negative ion of charge ?8e (see the figure below). (Take a = 4.88 µm, b = 4.24 µm, and ? = 59.5°.)

(a) Find the magnitude and direction of the resultant force on the electron. (Let right be the +x-direction. Measure the angle counter-clockwise from the +x-axis.) magnitude direction

(b) Find the magnitude and direction of the electron's instantaneous acceleration (Let right be the +x-direction. Measure the angle counter-clockwise from the +x-axis.) magnitude direction
