1.	A bob of mass M is hung using a string of length 2. A mass m moving with a velocity u pierces through the hot and emerges out with velocity u/3 horizontally. The frequency of small oscillations of the bob, considering A as amplitude is,
Answer» `1/(2pi) sqrt((3 m u)/(2MA))` `1/(2pi) sqrt((3 m)/(3MA))` `1/(2pi) ((2 m u)/(3 MA))` `1/(2pi)((3 m u)/(2 M A))` Answer :C
