As shown in the figure, a small particle of charge --3.95 x 10-7 pc and mass m 3.7x 10-17 dg has velocity vo 5.6473 x 10 kph as it enters a region of uniform magnetie field. the particle is observed to travel in the semicircular path shown, with radius r= 2.6 hm. calculate the magnitude and direction of the magnetic field in the region.
the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees.
double the distance = divide strength by 4
thermal energy is the answer
