1. Macie places Q1= 90C at the origin, Q2 = 50C at 40 cm from origin in positive x-direction and Q3 = -80C at 80 cm from origin in positive x direction. Find the force on Q2 due to the other two forces.

2. There is a -15 C charge on -5 cm of an x-axes and + 5 C charge on +2 cm of the same x-axes. Find the electric file at origin (magnitude and direction).

Show work for both please and thank you!
