## Homework Statement

A proton has a diameter of about 1fm. Estimate the minimum momentum in units of MeV/C of a quark confined in a proton.

## Homework Equations

## The Attempt at a Solution

I used the uncertainty relation [itex]\Delta[/itex]P[itex]\Delta[/itex]X ~ [itex]\frac{\hbar}{2}[/itex]

[itex]\Delta[/itex]P ~ [itex]\frac{\hbar}{2 x 1x10^{-15}}[/itex] = 5.276x10[itex]^{-20}[/itex] kgm/s

I'm unsure how to put this into MeV/C

thanks
