A body A weighin 22N is positioned on the end of a slender horizontal plank fixed at one end (mass of the plank is negligible). A force (vertically downwards) on A causes a deflection of 12.5mm. The natural angular frequency in rad/s of the body A is (nearly) ?
1)2 2)6 3)24 4)1.2
I got the answer as 28.3 rad/s. Can someone verify?
