# Oscillations of a Charge between Charges

EANDM-N5YWID

Two positive charges $Q=1\mu C$ are held at a fixed distance $d=10$ cm apart. A particle of mass $m=2$ g and charge $-q=-2\mu C$ is placed midway between them and given a small displacement $x\ll d$ in the direction perpendicular to the line joining the two positive charges, and released.

What is the period of the subsequent oscillatory motion of the particle?

A

0.037 s

B

0.3 s

C

30 s

D

We need to know $x$ to solve for the period.
