Three point charges are on the x axis: −6 µC at −3 m, 7 µC at the origin, and −5 µC at 3 m. Find the force on the ﬁrst charge. The value of the Coulomb constant is 8.98755 × 10^9 N · m^2/C^2.
A point charge of +1 µC is located at x = −2 cm and a second point charge of −8 µC is located at x = 6 cm. Where should a third charge of +1 µC be placed so that the electric ﬁeld at x = 0 cm is zero?
