Q1. After being accelerated to a speed of 1.7×10 5 m/s, the particle enters a uniform magnetic field of strength 1.00 T and travels in a circle of radius 35.0 cm (determined by observing where it hits the screen as shown in the figure). The results of this experiment allow one to find m/q.
Find the ratio m/q for this particle.
Q2. A charge of -3.0 nC is at the origin and a second charge of 11.0 nC is at x = 8.00 m. Find the magnitude and direction of the electric field halfway in between the two charges.
