An infinite sheet with a surface charge density of -2.1 micro-coulombs/m2 runs parallel to the x axis. Another infinite sheet a surface charge density of +2.1 micro-coulombs/m2 runs parallel to the y axis. A charge of -4.1 micro-coulombs moves at a 45 degree angle towards the negative sheet as shown in the sketch. If the initial velocity of the charge was 10.7 m/s and it's mass is 0.22 kg, how far does it travel before it stops in meters? Ignore the weight force.

An infinite sheet with a surface charge density of -2.1 micro-coulombs/m2 runs parallel to the x axis.  Another infinite sheet a surface charge density of  +2.1 micro-coulombs/m2  runs parallel to the y axis.  A charge of -4.1 micro-coulombs moves at a 45 degree angle towards the negative sheet as shown in the sketch.  If the initial velocity of the charge was 10.7 m/s and it's mass is 0.22 kg, how far does it travel before it stops in meters?  Ignore the weight force.
