Question

The paths of two particles (A and B) are shown in the diagram below. Their velocities are both initially to the right and in the plane of the page. They then enter a region of constant magnetic field. The magnetic field direction is perpendicular to the plane of the page. (Gravitational forces can be neglected.) If the charge on particle A is negative, the charge on particle B must be Submit Answer Tries 0/2 A must be Submit Answer If the two particles have the same mass and the speeds of the two particles are identical, the magnitude of the charge on particle the magnitude of the charge on B. Tries 0/2

Answer 1

B Magnetic force on a charge particle, - ² = qu x B for both particles A and B velocity, oo and magnetic field Be are some So, the wariance of force between A and depends only on the charge. A and B are going in the opposite direction, se force acting on these particle are opposite. If charge of A is negefive, then the charge of B should be positive • If the two particles are identical, then which has larger charge, will experience Larger force. Here, the force on the partiele A is greater than B, as particle A deflects more than B. So, Magnitude of the charge on particle a must be greater than the magnitude of charge on B.
