The four point charges shown in the diagram below are situated at the corners of a square. The charges Q1 and Q3 are + 2μC; Q2 is -6 μC, and Q is a positive charge.The resultant force on Q is:Select one:a.Directed away from q2.b.Directed away from q1.c.Directed towards q2.d.Directed away from q3.e.Zero.
Two point charges, q1 and q2 are separated by a distance d. For convenience, we will say that q1 is at the origin (0,0) on a coordinate system, q2 is at (d,0) and a reference point p is directly above q2 at a distance h at point (d,h). q1 has value 1μ𝜇C and q2 has value 8μ𝜇C. Take d= 1.1m and h= 0.7m.Note k=9×109Nm2/C2
