9. [***] Referring to Fig. 4, suppose Q₁, Q2, and Q4 are protons and are stuck in place on the
square, whose side length is 1mm. If Q3 is an electron and is allowed to move, what will the
magnitude of its instantaneous acceleration be?
(c) a = 4.8 x 108 m/s²
(d) a = 5.4 x 108 m/s²
(e) There is no acceleration in this configurarion since F2.ue=0.
