Two point charges, Q1 = 3.4 μC and Q2 = -1.3 μC , are placed on the x axis. Suppose that Q2 is placed at the origin, and Q1 is placed at the coordinate x1 = − 5.0 cm
(A) At what point(s) along the x axis is the electric field zero? Determine the x-coordinate(s) of the point(s).
(B) At what point(s) along the x axis is the potential zero? Determine the x-coordinate(s) of the point(s).
*Express your answer using two significant figures. If there is more than one answer, enter your answers in ascending order separated by commas.
Concept: we use the principle of superposition
to find the points at which field is zero, and for potential we put
the algebraic sum of the potential to zero find the
coordinates***************************************************************************************************
