The particle, confined to move along the x-axis, is moved by an external uniform electric field a small distance x along the axis (where x ≪ a), where it remains in equilibrium. the external field is then turned off and the particle oscillates along the x-axis on either side of the center of the ring. your supervisor observes your prototype and decides that the oscillation frequency of the charge needs to be increased by a factor of 27. (a) which parameter—m, q, q, or a—can be changed by the smallest percentage to achieve the desired frequency? m q q a correct: your answer is correct. you are correct. you should find that the frequency depends on a to the −3/2 power. (b) determine the percentage change. (enter the magnitude.)
