In a 1.25-t magnetic field directed vertically upward, a particle having a charge of magnitude 8.50 mc and initially moving northward at 4.75 km> s is deflected toward the east. (a) what is the sign of the charge of this particle? make a sketch to illustrate how you found your answer. (b) find the magnetic force on the particle.

As seen in a us weather map, the h (or high) and l (or low) symbols indicate regions where surface air pressures are high or low, respectively, compared to surrounding areas. an h is plotted where the air pressure is highest and an l is plotted where the air pressure is lowest. proceeding outward and away from the center of a high pressure system, the air pressure "
