Academics

In the x-y plane, a charge of -4.6 microcoulombs is on the x-axis at the point (-30cm,0cm), and a second charge of +7.2 microcoulombs is located on the y-axis at point (0cm,40cm).

A) calculate the magnitude and direction of the resultant electric field E at the origin (0cm,0cm)

B) calculate the magnitude and direction of the Electric Force F (using F=qE) acting on an ion of charge -3e if this particle were placed at the origin.
