Question

Three charged particles form a triangle: particle 1 with charge Q1=90.0 nC is at xy coordinates (0, 3.90 mm), particle 2 with charge Q2 is at (0, -3.90 mm), and particle 3 with charge q = 19.0 nC is at (4.10 mm, 0). What are (a) the x component and (b) the y component of electrostatic force on particle 3 due to the other two particles if Q2 is equal to 90.0 nC? What are (c) the x component and (d) the y component of electrostatic force on particle 3 due to the other two particles if Q₂ is equal to -90.0 nC,?

Answer 1

To calculate the electrostatic force on particle 3 due to particles 1 and 2, you can use Coulomb's law, which states that the force between two charged particles is given by:
