(b) Calculate the force that an electron experiences when placed at point C. (c) Give the direction of the acceleration of the electron just after placing it at point C.

Charges q1 and q2 are located on the corners of a rectangle. If width w=60 cm and length l=80.2 cm find the magnitude of the electric field (in N/C) at P when q1= 4.08 nC and q2=1.43 nC.

Just need #7, but need values from #6.

The electric field at a point in space is definedas the force per unit charge at that point inspace. We can write the electric field E ofa charge q at a distance d from that charge,experienced by a charge Q, asE =FQ= kqd2.The electric field has a direction such that itpoints toward negative charges and away frompositive charges.
