Question

two charged proteins P1 and P2 are located at positions (1m, 1m) and (-1m, 1m) respecively on a cartesian coordinate system. they have charges of 1.0 nC and -1.0 nC respectively. a key enzyme E1 which regulates an important biochemical pathway, is located at the origin of the coordinate system.

a) compute the electric potential V at the position of E1

b) draw a vector diagram for the electric field vector Etot, at the position of E1

c) show, or argue, that the y component of the electric field vector Etot,y at the position of E1, is equal to zero.

d) compute the electric field vector Etot, at the position of E1 (HINT: Etot is a vector)
