# Collapsing Bubble

**Classical Mechanics**Level pending

A conducting bubble of radius \( a\), thickness \(t (t<<a)\) has potential \(V\). Now the bubble collapses into a droplet.

The potential of the droplet \(V'\) can be given by:

\(V' = V {\left ( \frac{a}{mt} \right )}^{\frac{1}{n}}\), where \(m\) and \(n\) are integers.

Find the value of \(m - 2n\).
