Two point charges are placed on the x axis. (Figure 1)The first charge, q1q1 = 8.00 nCnC , is placed a distance 16.0 mmfrom the origin along the positive x axis; the second charge, q2q2 = 6.00 nCnC , is placed a distance 9.00 mm from the origin along the negative x axis. Calculate the electric field at point A, located at coordinates (0 mm, 12.0 mm ). Give the x and y components of the electric field as an ordered pair. Express your answer in newtons per coulomb to three significant figures.

the diagram as shown. The charges of each marble are q₁6.50 μC, 9₂ 1.17 pc, and q3 -1.79 μC. Marble q, is a distance r = 3.00 cm to the left of the marble q₂, while marble q, 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 = 1.00 cm to the left of the center marble. N/C 4 observation point 92 r₂ = 0m Another marble is placed 1 cm to the left of the middleimarble. If this new marble has a charge of 3.71 µC, calculate magnitude and direction of the force on it. 77. x magnitude

Three charges are placed along the x-axis: q1 = 3.00 µC at X1 = -20.0 cm, q2 = -5.00 µC at x2 = 10.0 cm, and q3 = 6.00 µC at x3 = 25.00 cm. Determine the magnitude of the electric field at the origin. O 4 69x106 N/C O 2 96x106 N/C O 6 04x106 N/C O 4.31x106 N/C

There are two point charges q1=(7.000x10^0) µC and q2=(-3.0000x10^0) µC. q1 is located at origin (0, 0). q2 is located at (4.00x10^0) m,(5.000x10^0) m). Now we place another point charge q3 = (1.0000x10^1) µC at ((4.00x10^0) m, 0), i.e. q3 is right underneath of q2. Please calculated the X-component of the electrostatic force on q3 . Give your answer in the unit of N with 3 sf. Note: Use the sign to represent the direction, for example -2.11x10^-4 means the force is on the negative x direction.
