Question

An electron is near a positve ion of charge +9e and a negative ion of charge -8e (see figure). (Take a = 4.40 um, b=4.20 um, theta = 66 degrees)

(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.)

(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.)

An electron is near a positive ion of charge +9e and a negative ion of charge -8e (see the figure below). (Take a =
4.40 µm, b = 4.20 µm, and 0 = 66.0°.)

Expert Solution

Step 1

Charge on electron = - 1.6 × 10^-19C

Q₁= - 8 e = - 8 × 1.6 × 10^-19

= 12.8 × 10^-19C

Q₂= + 9e =+ 9 × 1.6 × 10^-19C

= 14.4 × 10^-19C
