Answer:
Magnitude of force, F = 11 Newtons
Step-by-step explanation:
Charge 1,
![q_1=5.3\ \mu C=5.3* 10^(-6)\ C](https://img.qammunity.org/2020/formulas/physics/college/2u5x1tp4qa6ls1lyvf62niocshanpd5tx0.png)
Charge 2,
![q_2=11.2\ \mu C=11.2* 10^(-6)\ C](https://img.qammunity.org/2020/formulas/physics/college/vwt9mqi2rxzknxmqp5mgeqlqfql1luodno.png)
The separation between the charges is, r = 0.22 m
We have to find the magnitude of the force between two point charges. It can be calculated using the formula as :
![F=k(q_1q_2)/(r^2)](https://img.qammunity.org/2020/formulas/physics/high-school/uk8f4z91yssptetrk6ebnulp741i636gb7.png)
![F=9* 10^9* (5.3* 10^(-6)\ C* 11.2* 10^(-6)\ C)/((0.22\ m)^2)](https://img.qammunity.org/2020/formulas/physics/college/91jg10o8ertsmya5yo47fldllnsfcadj43.png)
F = 11.03 N
or
F = 11 Newtons
Hence, this is the required solution.
