A uniform solid cylinder of mass 'm' and radius 'r' rolls along an inclined rough plane of inclination 45°. If it starts to roll from rest from the top of the plane then the linear acceleration of the cylinder axis will be :-
1
\(\frac{1}{\sqrt{2}} \mathrm{~g}\)
2
\(\frac{1}{3\sqrt{2}} \mathrm{~g}\)
3
\(\frac{\sqrt{2} \mathrm{~g}}{3}\)
4
√2 g
