Can an object with constant also be accelerating?

The velocity vector is constant in magnitude but changing in direction. Because the speed is constant for such a motion, many students have the misconception that there is no acceleration. ... For this reason, it can be safely concluded that an object moving in a circle at constant speed is indeed accelerating.

Explanation:

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)

beta is electron from nucleus

something from nucleus has changed, but charge must be same for cons of charge
