The dark quarter-circle indicates the path of the negatively charged particle as it passes through a region containing a uniform magnetic field.
(A) what is the direction of the magnetic field in the shaded region? Explain your reasoning.
(B) if we doubled the magnitude of the uniform magnetic field, how will the path change? Explain your reasoning.
(C) if we replace the original particle with a positive particle of the same mass and same magnitude charge as the original native charge, how will the path change? explain your reasoning.
