Question

A point charge q1 = -1.9 C is at the origin, and a second point charge q2 = +5.3 C is at the point x = 0.8 m, y = 2.6 m.

(a) Find the x and y coordinates of the position at which an electron would be in equilibrium.
x   = _____m
y   = _____ m

(b) Find the x and y coordinates of the position at which a proton would be in equilibrium.
x   = _____m
y   = _____m

(c) Suppose the charges q1 and q2 were both doubled. How would your answers change?
The electron would be in equilibrium at the following point.
x   = ____m
y   = ____ m

The proton would be in equilibrium at the following point.
x   = ____ m
y   = _____ m
