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.
Assume the mass density of Earth from the center to r= R_cm (radius of the core mantle boundary) is d_cm and from R_cm until the surface r=R_e the density is d_e. Using these densities, determine the gravitational potential energy of the Earth
