Q1. In New England, the horizontal component of the Earth`s magnetic field has a magnitude of 1.4 x 10-5 T. An electron is shot vertically straight up from the ground with a speed of 3.9 x 10^6 m/s. What is the magnitude of acceleration caused by the magnetic force? Overlook the gravitational force acting on electron.
Q2. A 3.00 kg mass resting on a level table top is pulled along by a horizontal force of 16 N and accelerates at 4.00 meters per second per second. What is the force of friction between block and table?
