Two positive charges, Q1=16.2 C and Q2=25.1 C are placed a distance d=43.6 cm apart
The magnitude of the force experienced by Q1 due to the charge Q2 is F=1.9226e13 N
A third charge, Q3=-36.5 C, is placed between the two charges Q1 and Q2. If there is no force on Q3, what is the distance between Q1 and Q3? (in cm)
Can you breifly explain the step as well?
