Question
1. (6 pointsForce and acceleration Note: I may change the relative charges and masses of objects A and B D1-SCT35: Two NEGATIVELY CHARGED PARTICLESACCELERATION Two negatively charged particles labeled A and B are separated by a distance x The particles have different charges and masses as shown Three students are discussing what will happen just after the particles are released Antonio fnt 3/m "The magnitude of the force that A exerts on B will be the same as the magnitude of the force that E exerts on A. Since A has less mass, it will have a larger acceleration. "The magnitude of the force on A by B is greater than the magnitude of the force on B by A since B has more mass. So A will have the largest acceleration." "A has more charge but it has less mass. The larger mass of B is exactly compensated for by the larger charge of A. The acceleration of both will be the same." Brenda: Cho: With which of these students do you agree? Antonio Explain your reasoning. BrendaCho_ None of themExplanation / Answer
Answer : Antonia
magnitude of electrostaic force between two charges Fes = KqQ/R2
magnitude of gravitational force between two mass Fg = GmM/R2
hence magnitude of force on both charges are same but A has small mass so that A has greater acceleration fron F= ma
