1.
Four electric charges are arranged in the following way:a-1 nC charge located at(0.25m,0.25 m),a2 nC charge located at(-0.5m,0.5 m),a-2 nC charge located at (0m,0.25m),and a1nC charge located at0.25m,0m).
a
What is the electricfield located at the origin?
b.
if an electron were placed at the origin,what would be the force acting on the electron by the four charges?
What would be the acceleration of the electron?
