A negatively charged particle in a uniform magnetic
field follows a circular path. The particle's speed is
240 m/s, the magnitude of the magnetic field is 0.28 T, and the
radius of the path is 830 m. a) Determine the mass of the
particle, given that its charge has a magnitude of 9.6 x 10^-4 C.
b) Choose the sketch which correctly shows the direction of the
magnetic field (in red) and the direction of the particle's
circular motion (in green)....

Understand how to find the equation of motion of a particle undergoing uniform circular motion. Consider a particle--the small red block in the figure--that is constrained to move in a circle of radius R. We can specify its position solely by θ(t), the angle that the vector from the origin to the block makes with our chosen reference axis at time t. Following the standard conventions we measure θ(t) in the counterclockwise direction from the positive x axis. (Figure 1)...

When an object moves in uniform circular motion, the direction of its acceleration is is directed toward the center of its circular path. depends on the speed of the object. in the opposite direction of its velocity vector. is directed away from the center of its circular path. in the same direction as its velocity vector

A particle moves horizontally in uniform circular motion, over a horizontal xy plane. At one instant, it moves through the point with coordinates (x, y) with a velocity of vi and an acceleration of -aj. In these expressions, v and a are the speed and the magnitude of acceleration, respectively, and thus are positive quantities. In terms of the variables given, what are the coordinates (a) xo and (b) Yo of the center of the circular path? (a) Xo =...
