Two point charges are placed along a horizontal axis with the following values and positions: +6.0 µC at x = 0 cm and 24.0 µC at x = 60 cm. At what point along the x axis is the electric field zero?

It won't be between the charges, because both charges produce an Efield in the same direction there. Look for it to be along the X axis, at a point x = a, where
6/a^2 = 24/(60 + a)^2
(60+a)/a = sqrt(4) = 2
60/a + 1 = 2
a = 60 cm
