Two point charges are placed on the x-axis as follows: charge q1= 3.96 is located at x=0.202 , and charge q2= 4.99 is at x=-0.302 .what is the magnitude of the total force exerted by these two charges on a negative point charge q3= -5.95 that is placed at the origin?

The solution to your problem is as follows:

Since,

F = Σ kQq / d² 

Then,

F = 8.99e9N·m²/C² * (5.20nC/(0.400m)² - 3.85nC/(0.195m)²) * -0.615nC 
F = 3.8e-7 N 

Therefore, the magnitude of the total force exerted by these two charges on a negative point charge is 3.8e-7 N.
