Apoint charge q1 = -2.3 μc is located at the origin of a co-ordinate system. another point charge q2 = 6.2 μc is located along the x-axis at a distance x2 = 9.9 cm from q1.

-13.09 N

Explanation:

Hello!

With Coulomb's law, the force of attraction between two charges can be calculated:

F=(K*q_1*q_2)/r^2

K=9*〖10〗^9  (N*m^2)/C^2

9,9 cm = 0,099 m

-2,3µC= -2,3*〖10〗^-6 C

6,2µC= 6,2*〖10〗^-6 C

By simplifying units the force remains in Newton.
