Angular acceleration of an object is given by

[tex]\begin{gathered} \alpha=\text{ }\frac{\omega}{t} \\ \alpha=\text{ }\frac{v}{rt}\begin{cases}w={\frac{v}{r}} \\ \end{cases} \\ \end{gathered}[/tex]

Here,

α= angular acceleration;

ω= angular velocity;

v= linear velocity;

t= time

Now according to above relation we can conclude that when speed is doubled and radius stays unchanged then acceleration will be doubled .

Correct answer is :- A)It doubles
