A point charge of -4.00 nC is at the origin, and a second point charge of 6.00 nC is on the x axis at x= 0.800 m. Find the magnitude and direction of the electric field at each of the following points on the x axis. EA= 1050 N/C (x2) EB= 197 N/C (x3)  (E) x4 = -24.0 cm. Express your answer in newtons per coulomb. (F) The field at point x4 is directed in the +x direction -x direction

How do you find the total charge?

A charge of -0.7x10-6C is placed at x = 0m. A second charge of 2x10-6C is placed at x = 0.22m. What is the electric field (size and direction) at x=0.050m?

a 2.8-uC point charge is places in an external uniform electrric field of 2.4E4 N/C. At what distance from the charge is the net  electric field zero

There is a 6.5 pC point charge. What is the magnitude of the electric field (in N/C) 70.4 mm away from this charge?

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.
