After being accelerated to a speed of 1.76×105m/s , the particle enters a uniform magnetic field of strength 0.800T and travels in a circle of radius 35.0cm (determined by observing where it hits the screen as shown in the figure). screen as The results of this experiment allow one to find m/q. Find the ratio m/q for this particle.
An 18.0 g rifle bullet travelling 245 m/s buries itself in a 3.50 kg pendulum hanging on a 3.00 m long string, which makes the pendulum swing upward in an arc. Find out the vertical and horizontal components of the pendulum's displacement.
