How do they do it?

Electricity and Magnetism Level 3

Let a charge \(\displaystyle Q\) be held fixed in space. Another charge \(\displaystyle q\) of mass \(m\) is thrown with a velocity of \(\displaystyle v\) from an infinitely far place, as shown in the figure, such that it is at a separation of \(\displaystyle d\) initially.

Find the minimum distance (in m) between the two charges.

Details and Assumptions

\(\bullet\) \(\displaystyle Q = 5\ \mu C\)
\(\bullet\) \(\displaystyle q = 1\ \mu C\)
\(\bullet\) \(\displaystyle d = 3\text{ cm}\)
\(\bullet\) \(\displaystyle v = 2 \text{ m/sec}\)
\(\bullet\) \(\displaystyle m = 1\text{ g}\)
