44,512,992 mm/m. Hopefully...
Answer:
I think the answer 1
Explanation:
im probably wrong too i dont know
Answer:

Explanation:
Here we know that for the given system of charge we have no loss of energy as there is no friction force on it
So we will have


now we know when particle will reach the closest distance then due to electrostatic repulsion the speed will become zero.
So we have



so distance moved by the particle is given as



Since this a position vs time graph, the velocity will be the slope of the line.
(5-3) / (3-0)
2/3 m/s
.6666 m/s
