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 (in t) magnetic field is needed to hold antiprotons, moving at 5.70 ✕ 107 m/s in a circular path 2.60 m in radius? antiprotons have the same mass as protons but the opposite (negative) charge. (enter the magnitude.)

0.23 T

Explanation:

The magnetic force exerted on the antiproton must be equal to the centripetal force, since it is a circular motion, therefore we can write:

where

is the charge of the antiprotons

is the speed of the antiprotons

B is the magnitude of the magnetic field

is the antiproton mass

r = 2.60 m is the radius of the orbit

Solving the equation for B, we find the strength of the magnetic field:

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)
