Q1. A magnetic field has a magnitude of 1.20 x 10-3 T, and an electric field has a magnitude of 4.90 x 10^3 N/C. Both fields point in the same direction. A positive 1.8-µC charge moves at a speed of 2.40 x 10^6 m/s in a direction that is perpendicular to both fields. Determine the magnitude of the net force that acts on charge.

Q2. A 3.20 kg block of wood sits on a table. A 2.50 g bullet, fired horizontally at a speed of 600 m/s, goes completely through the block, emerging at the speed of 180m/s. What is the speed of the block immediately after the bullet exits?
