Coulomb's Law gives us an expression for the electric field caused by a point charge with magnitude . Suppose we have several point charges. The electric field at a location is the vector sum of point charge contributions. Consider a standard x-y coordinate system. A small ball with charge -3.6 nC is located on the x axis at x1 = 8.5 cm. A second ball of charge -8.7 nC is located at x2 = -3.0 cm and y2 = 4.0 cm.

(a) Find the components of the net electric field at the origin. Ex and Ey

(b) Find the magnitude and direction of the net electric field at the origin.

/E/ at direction (from +x axis) ___ degrees

Expert Solution

The concept used is of electric field due to point charge and vector algebra , initially i find out the direction of the electric field at the origin due to the individual charges , after that i calculated the x and y components of electric field at the origin and then take the resultant of the electric field along x and y axis , then find calculate the magnitude and direction of the net electric field vector at the origin .
