In the figure particle 1 of charge +4e is above a floor

In the figure, particle 1 of charge +4e is above a floor by distance d1 = 2.00 mm and particle 2 of charge +6e is on the floor, at distance d2 = 6.00 mm horizontally from particle 1.What is the x component of the electrostatic force on particle 2 due to particle 1?

In the figure particle 1 of charge +6e is above a floor by distance d1 = 3.10 mm and particle 2
of charge +7e is on the floor, at distance d2 = 7.10 mm horizontally from particle 1. What is
the x component of the electrostatic force on particle 2 due to particle 1?
