Two particles are fixed to an *x* axis: particle 1 of charge -1.90 × 10^{-7} C is at the origin and particle 2 of charge +1.90 × 10^{-7} C is at *x*_{2} = 21.1 cm. Midway between the particles, what is the magnitude of the net electric field?

Step 1

The electric field lines out of the positive charge and toward the negative charge.

Write the expression for electric field due to a point charge.

Step 2

Using the equation above, the magnitude of the electric field due to a charge at origin can be calculated as follows.

Step 3

Using the equation above, the magnitude of the electric fiel...
