A string of length l=1m and tensioned by a weight M = 4kg has two masses, each of mass = 10g, attached to it at distance `l/4` and `3/4` from one of the ends. Find the frequency of oscillations of the masses in the two cases.
a) When the masses are displaced equally in the same direction b) when the masses are displaced equally in opposite directions.

Answer

`(a)(1)/(2pi)sqrt((4Mg)/(ml)),(b)(1)/(2pi)sqrt((8Mg)/(ml))`
