Question

A point charge q1 = -1.6 C is at the origin, and a second pointcharge q2 = +4.6 C is at the point x = 1.0 m, y = 2.0 m.
(a) Find the x and y coordinates of the position at which anelectron would be in equilibrium.
x ______ = 1 m
y ______ = 2 m

(b) Find the x and y coordinates of the position at which a protonwould be in equilibrium.
x______ = 3 m
y______ = 4 m

(c) Suppose the charges q1 and q2 were both doubled. How would youranswers change?
The electron would be in equilibrium at the following point.
x ______ = 5 m
y_______ = 6 m

The proton would be in equilibrium at the following point.
x_____ = 7 m
y______ = 8 m
