An equilateral triangle with sides 89 m has charges +2 µC, −2 µC, and −10.2 µC at its vertices and charge +20.4 µC at the midpoint on its side between the vertices with charges +2 µC and −2 µC. 89 m 44.5 m 44.5 m 89 m +2 µC −2 µC −10.2 µC P +20.4 µC What is the magnitude of the x-component of the electric field at P, the point forming a second equilateral triangle with +2 µC and −2 µC? The permittivity of free space is 8.85419 × 10−12 C 2 /N/m2 . Answer in units of N/C.
