of charges +75 , +48 and -85 μC are places in a line (see the figure ) the center one is 0.35 m from each of the others calcula

3) A-9.0-uC charge is placed 12.4 cm from a charge q, the force between the two charges is 840 N. What is the value of q?

Point charges qi -65 µC and q2 = -50 µC are placed 2.0 m apart. What is the force on a third charge q3 = -40 µC placed midway between q1 and q2? Magnitude: F number (rtol=0.03, atol=0) N Direction: towards q2 towards q1 the force is zero

3) a)What are the magnitude and direction of the force exerted on a 4.41 pC charge by a 184 N/C electric field that points due east? magnitude direction ---Select- v b) You charge a piece of aluminum foil (mass =7.46 g) by touching it to a charged rod. The charged rod gives the aluminum foil a charge of 13 µC. Your professor brings a charged plate over and tells you to put the aluminum foil on top of the plate. To your surprise the aluminum foil hovers motionless in the air above it! Calculate the value of the electric field from the charged plate (assume it is a uniform field and the aluminum foil is a point charge). magnitude N/C direction -Select-- v

What is the force ?⃗ on the -10 [nC] charge? Give your answer as a magnitude and an angle measured from the +x axis

Common transparent tape becomes charged when pulled from a dispenser. If one piece is placed above another, the repulsive force can be great enough to support the top piece's weight. Assuming equal point charges (only an approximation), calculate the magnitude of the charge if electrostatic force is great enough to support the weight of a 16.3 mg piece of tape held 0.64 cm above another. (The magnitude of this charge is consistent with what is typical of static electricity.) (C)

Three charges are fixed to an x,y coordinates system. A charge of +15uC is on the y -axis at y= 4m. A charge of +12uC is at the origin. Lastly a charge of -15 uC is on the x -axis at x= 3m. Determine the magnitude and direction of electrostatic force on the charge at x = 3m

Determine the net electric force acting on a 3.0 µC charge by two charges. The first charge is -2.0 µC and is located 10 cm to the left of the 3.0 µC charge. The second charge is 4.0 µC and is located 8 cm to the right of the 3.0 µC charge.
