1.	Springs of constants k, 2k, 4k, 8k, 16k ...... are connected in series. The mass 'm' kg is attached to the lower end of the last spring and the system is allowed to vibrate. The frequency of oscillation is
Answer» `(1)/(pi)sqrt((m)/(2k))` `(1)/(2PI)sqrt((K)/(2m))` `(1)/(2pi)sqrt((2m)/(2k))` `(1)/(2pi)sqrt((4M)/(k))` Answer :B
