LEARN MORE REMARKS The initial acceleration is also in the positivez-direction. Because the direction of however, the subseq 1 to find the direction, it was particle accelerates in the opposite direction. changes. uent direction of the magnetic force also changes. In applying right-hand rule number important to take into consideration the charge. A negatively charged Can a constant magnetic field change the speed of a charged particle? Explain. (Select all QUESTION that apply.) O Yes, because the non-zero net force it produces causes acceleration. O Yes, because a change in direction of motion is a change in speed. O No, because the instantaneous acceleration it produces is perpendicular to the instantaneous velocity. No, because the magnetic force does not work on the particle, and therefore causes no change in the particle's kinetic energy. O No, because the magnetic field always points in the direction of the velocityExplanation / Answer
in a magnetic field a charged particle motion under a circular path. a force F=qVB works on it but it causes a centrifugal force for the particle and it changes the direction of the moving charged particle, but because the force is working perpendicular to the direction of current velocity AND for the change in magnitude we have to force in the direction of current velocity so it cannot change in the magnitude of the velocity so IN A CONSTANT MAGNETIC FIELD CHANGE IN SPEED OF A CHARGED PARTICLE IS ZERO, MEANS IT REMAINS CONSTANT.
in given statements-
3) no because the instantaneous acceleration it produces is perpendicular to the instantaneous velocity.
