At a certain point on Earth, the horizontal component of Earth’s magnetic field is 2.5 × 10-5 T due to north. An electron moves eastward with just the right speed, so the magnetic force on it balances its weight. Find the speed of the electron.
What is the magnitude of the field if a charge of 10 C travelling at a speed of 8 × 106 m/s in a direction perpendicular to a magnetic field experiences a magnetic force of 8.7 × 10-3 N?
