![Three charges reside on the vertices of an equilateral triangle with 25.0-cm
sides, as shown. Suppose that qb = 10.00 µC and qc = -5.00 µC. (a) What
is the electric field (magnitude and direction) at q's position? (b) Determine
the force there if qa = 1.50 nC.](https://content.bartleby.com/qna-images/question/2baa15e1-437a-4e4a-8bc8-abfccdab9f8b/67b62530-657d-4429-8c82-21782be9a849/otxlcda_thumbnail.png)
