Answer:
The correct answer is D
Explanation:
The expression for the accelerated ion is
a =[tex]\frac{v_f - v_o}{ \Delta t}[/tex]
therefore to find the variation of time is needed, which is a data given in the problem.
It also needs to be emptied of speed, which is not given.
Consequently we cannot find the acceleration in this exercise.
The correct answer is D
