Step-by-Step

1. Coulomb's Law

F=kq1q2r2=(8.988×109)(1×10−6)(1×10−6)(0.1)2F = k\frac{q_1 q_2}{r^2} = (8.988 \times 10^{9})\frac{(1 \times 10^{-6})(1 \times 10^{-6})}{(0.1)^2}

2. Force

F=0.8987 NF = 0.8987 \text{ N}

3. Electric field due to q₁

E=k∣q1∣r2=8.987×105 N/CE = k\frac{|q_1|}{r^2} = 8.987 \times 10^{5} \text{ N/C}
