Field and force with three charges
At a particular moment, three small charged balls, one negative and two positive, are located as shown in the figure. Q1 = 2 nC, Q2 = 6nC, and Q3 = -4 nC.
Q1 = 2 nC = 2*10-9 C
Q2 = 6 nC = 6*10-9 C
Q2 = -4 nC = -4*10-9 C
k = 8.988*109 N*m2/C2 is Coulomb's constant
(a1) What is the electric field at the location of Q1, due to Q2?
