Question

Three charged marbles are glued to a nonconducting surface and are placed in the diagram as shown. The charges of each marble are q₁ = 6.55 µC, q₂ = 1.73 µC, and

q₃ = −2.33 µC.

Marble q₁ is a distance r₁ = 3.00 cm to the left of the marble q₂, while marble q₃ is a distance r₃ = 2.00 cm to the right of the marble q₂, as shown. Calculate the magnitude of the electric field a distance r' = 1.00 cm to the left of the center marble.

Another marble is placed 1 cm to the left of the middle marble. If this new marble has a charge of

−3.61 µC,

calculate magnitude and direction of the force on it.
