an elecrton is placed in a uniform electric field of 232 n/c charge. if the electron is at rest at the origin of t=0 and the field is in the positive direction, what are the x and y coordinates of the electron at t=2.3 ns

physics 
bobpursley,
E=232N/coulomb
F=m*a=232*e where e is the charge on the electron. Solve for acceleration, then use displacement= a*t
Now direction....If E is positive, the electron is in the negative direction. You did not state whether field was in +x or+y direction. Remember, the direction of E is the same direction that a +test charge will experience a force. charges are in the opposite direction.
