(A) A particle of charge 40.00 C travels along the negative x-axis with a speed of 100.00 m/s. Calculate the magnitude of the magnetic field at the point (0.26 cm, -0.97 cm) when the particle is located at the origin
(B) A proton is travelling through the point (0.26 cm, -0.97 cm) with speed 4.00×105 m/s. If the proton's velocity is directed at an angle of 77.00 degrees above the horizontal, what is the magnitude of the magnetic force on the proton due to the field vector you calculated earlier?
(C) What is the direction of the magnetic force on the proton (answer should be an angle relative to the horizontal direction. Use a negative angle if it is below the horizontal)?
