Question

Three point charges are arranged along the *x*-axis.
Charge *q*_{1} = +3.75 µC is at the origin, and
charge *q*_{2} = -5.25 µC is at *x* = 0.300
m. Charge *q*_{3} = -9.00 µC. Where is
*q*_{3} located if the net force on
*q*_{1} is 6.00 N in the −*x*-direction?

Answer #1

equate the resultant force on q1 = 6 N.

the charge q1 is at centre.let me explain..

the charge q1 is positive and the charge q2 ia negative and at the right side of q1 ao the force between the q1 and q2 will be in positive x direction due to attractive forcebetween the different charge particles so the other charge q3 should be left of q1 as the q3 is negative and so the attractive force should be more than the q2 charge.

6. Three point charges are arranged along the x-axis. Charge q1
= -2 uC is at x=0.5 m, and charge q2= 5 uC is at x=-0.5m. At what
position(s) can the third charge q3=1 uC be located if we want the
net force on q3 to be zero

Three charges lie along the x-axis. One positive charge, q1 = 25
uC is at x = 0.25 m. Another charge, q2 = -5.0 uC, is located at
the origin. A third charge, q3 = -35 uC, is placed so that q2 is in
electrostatic equilibrium with q1 and q3. How large must the
electrostatic force between q2 and q3 be to balance the force
between q1 and q2?
