There is a positive charge Q at x = 5 cm on the x-axis, and a negative charge -2Q at x = 15 cm on the x-axis. What are the total electric fleld and electric potential at x = 10 cm on the x- axis? Assume the usual convention for defining the potential of a point charge. E (vector) points to positive x, V is negative E (vector) points to positive x, V is positive E (vector) points to negative x, V is negative E (vector) is zero, V is zero E (vector) is zero, V s negative. E vector) points to negative x Vis postive
