A bicycle wheel rotates at a constant 25 rev/min. Is its angular velocity decreasing, increasing, or constant?

you have to draw the persons position over there

the answer is neither ball has a charge.

because if they were both positively charged, they will repel each other.

if they were positively and negatively charged, they will seek.
