Aphoton of wavelength 0.1382 nm travels in the positive x direction and scatters from a stationary electron placed at the origin. the wavelength of the scattered photon is 0.1403 nm. (a) what is the final speed of the electron? m/s (b) what angle does the electron's final velocity make with the x axis? degrees

Rank the six combinations of electric charges on the basis of the electric force acting on q1. define forces pointing to the right as positive and forces pointing to the left as negative. rank positive forces as larger than negative forces. q1,q2,q3 = positive(+) q1 = + q2 = + q3 = - q1 = + q2= - q3= + q1= - q2= + q3= + q1= + q2= - q3= - q1,q2,q3 = negative
