General Physics 2 - Electric Field

Question

Good day to everyone! May I help with these questions, before anything else... please do provide an in-depth step-by-step explanation and a clear final answer.

a.) Given two charges 𝑄1 = -1.5 x 10^-6 𝐶 and 𝑄2 = 2.3 x 10^-9 𝐶... Find the electric field on point A, B, and C, given in the figure.

b.) Convert the following in Coulomb (C).

1. 3.15 𝜇𝐶 = ?
2. 3.15 𝑛𝐶 = ?

Thank you so much and much appreciated!

Answer 1

1) 3.15𝜇𝐶

Since 1𝜇𝐶= 10^-6 C

hence 3.15 𝜇𝐶= 3.15×10^-6 C

2) 3.15nC

1nC = 10^-9

So 3.15nC =3.15× 10^-9 C
