B E Figure 4 In Figure 4 above a negatively charged particle of mass m and charge q=-7.5 x 10°C performs a circular motion horizontally in a clockwise direction. This motion is performed in a region with uniform magnetic field. Both magnetic fields and electric fields point downwards and have the strengths of B=0.45 T and E=150 NC respectively. Draw a free body diagram to show all forces acting on the charged particle. Calculate the period of revolution. Suppose that the electric field is removed, compare both situations.

Part A At a particular instant, charge q1 = 4.50x10-6 C is at the point (0, 0.250 m, 0) and has velocity (9.20 × 105 m/s) î. Charge q2 = -2.60x10-6 C is at the point (0.150 m, 0, 0) and has velocity v2 = At this instant, what is the magnetic force that qi exerts on q2?

Part a and C please and thank you When a particle of charge q>0 moves with a velocity of v⃗1 at 45.0∘ from the +x-axis in the xy-plane, a uniform magnetic field exerts a force F⃗1 along the−z-axis (the figure (Figure 1)). When the same particle moves with a velocity v⃗2 with the same magnitude as v⃗1 but along the +z-axis, a force F⃗2 of magnitude F2 is exerted on it along the +x-axis. Part A What is the magnitude (in terms of q, v1, and F2) of the magnetic field? Part C What is the magnitude of F⃗1 in terms of F2?
