Viewers of Star Trek hear of an antimatter drive on the Starship Enterprise. One possibility for such a futuristic energy source is to store antimatter charged particles in a vacuum chamber, circulating in a magnetic field, and then extract them as needed. Antimatter annihilates with normal matter, producing pure energy. What strength magnetic field is needed to hold antiprotons, moving at $4.98\times 10^7\mathrm{m}/\mathrm{s}$ in a circular path $2.02\mathrm{m}$ in radius? Antiprotons have the same mass as protons but the opposite (negative) charge. $\mathrm{T}$
