Dec 30, 2015 · Hence, no energy is gained or lost by the particle moving through the magnetic field and the particle’s speed is always constant. Since the force is of constant magnitude and it always at right angles to the displacement, the conditions are met for circular motion. Hence, the magnetic force on a moving charge provides a centripetal force to ...

v i. Would mean 'velocity initial' or 'the initial velocity'. Now you are just as likely to see the subscript 'o' meaning 'original' used for exactly the same concept, the first, initial, or original. This symbol: v o. Would mean 'velocity original' or 'the original velocity'. So the subscripts 'i' and 'o' carry the same concept: v i is the ...

Dec 11, 2020 · A whopping 16,000 m/s exhaust velocity, compared to only 8,000 m/s or so from H 2. This is because the exhaust velocity increases as the mass of the propellant particle decreases. Obviously an H 1 atom has half the mass of an H 2 molecule. What's the catch? The problem is that it desperately wants to recombine into H 2. In other words the ...
