Q1. After being accelerated to a speed of 1.84×105, the particle enters a uniform magnetic field of strength 1.00 and travels in a circle of radius 35.0. The results of this experiment allow one to find.
Find out the ratio for the particle.
Q2. A bumper car with mass m1 = 100 kg is moving to the right with the velocity of v1 = 4.7 m/s. A second bumper car with mass m2 = 82 kg is moving to the left with the velocity of v2 = -3.8 m/s. The two cars have an elastic collision. Suppose the surface is frictionless.
