Question 1
A charged particle with a charge of +2 C is traveling at a speed of 10 m/s through a magnetic field of strength 0.2 T. Calculate the magnetic force acting on it when the angle ΞΈ is 60 degrees.
π‘ Hint: Use the sine of 60 degrees for your calculations.
Question 2
Describe how and why the magnetic field strength changes as you move away from a current-carrying wire, using the formula B = ΞΌβ I / (2Οr). Calculate the field strength from a wire carrying 3 A at a distance of 0.3 m.
π‘ Hint: Focus on the relationship between r and B, and compute based on the constants provided.
