Express your answer in newtons per coulomb to three figures. Keep in mind that an x component that points to the right is positive and a y component that Constants charge, 1 8.00 nC is placed a distance 16 0 m from the origin along the positive x axis, the second charge, 92 6.00 nC, is placed a distance 9.00 m from the origin along the negative x axis View Available Hint(s) Figure 1 of 2 Submit Part B Now, assume that charge q2 is negative. 2 -6 aC. (Fiqure 2yWha is the net electric field at the orgn, pont 07 Give the x igures. Keep in mind that an x component that points to the rnight is positve and a y component that points upward is positive. View Available Hint(s) d y components of the electric field as an ordered pair. Express your answer in newtons per coulomb to three significant (+16111. 0 m)

Explanation / Answer

a) When both charges are positive. The field due to charge on + x axis will point to the negative and field due to charge on -x axis will point to the positive

so, E1 = kq1 / r2

E1 = - 2812.5

E2 = 6666.67

so, Enet = Eox = 3854 N/C,

Eoy = 0 N/C

B)

For part B, electric field points in same direction,

so,

Eox = 2812.5 + 6666.67

Eox = 9479.17 N/C

Eoy = 0 N/C
