Physics
Two particles are fixed on an x axis. particle 1 of charge 69.9 μc is located at x = -4.32 cm; particle 2 of charge q is located at x = 36.1 cm. particle 3 of charge magnitude 22.1 μc is released from rest on the y axis at y = 4.32 cm. what is the value of q if the initial acceleration of particle 3 is in the positive direction of (a) the x axis and (b) the y axis?

Explanation:
Given:
Charge on particle(1) =![69.9\ \mu C](/tpl/images/0223/5035/f07ff.png)
Charge on particle(3) =![22.1\ \mu C](/tpl/images/0223/5035/2dc26.png)
Angle made by particle 1 with the x axis
Angle made by particle 3 with the x axis
a) If the acceleration particle 3 is along the positive x axis then then it means the net force on the charge along y axis is zero so
b) If the acceleration particle 3 is along the positive y axis then then it means the net force on the charge along x axis is zero so
