2) A charge of -4.00 micro C is fixed in place. From horizontal distance of 55.0 cm, a particle of mass 2.50*10^-3kg and charge -3.00 micro C is fired with initial speed of 15.0 m/s directly toward the fixed charge. How far does the particle travel before it stops and begins to return back?
4) In question 3), calculate the work done needed to move a 1.5 micro C test charge from point B to D.
