4. ### What is the velocity of the particle when the particle reaches 3R?

EDIT If we assume the object can’t move in the y-direction then the velocity remains constant (5.0*10^4 m/s). That's because of symmetry.  The x-components of attraction and repulsion forces (from the upper and lower halves of the ring) have equal...
