(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A relativistic particle travels a length of 3*10^-3 m before decaying.The decay process of this particle is dominated by.....

(a)Strong interactions

(b)EM interactions

(c)weak interactions

(d)gravitational interactions.

2. Relevant equations

3. The attempt at a solution

Since the question says the particle is relativistic, i took its velocity = c

then,

t = x/v = 10^{-11}

which is the timescale for weak interactions.

But the text says the answer is strong interaction.

Then wheres the mistake?
