A thin strip 
long is on a 
shaped wire of negligible resistance and it is connected to a spring of spring constant 
(see figure). The assembly is kept in a uniform magnetic field of 
. If the strip is pulled from its equilibrium position and released, the number of oscillations
it performs before its amplitude decreases by a factor of e is 
. If the mass of the strip is 
, its resistance 
and air drag negligible, 
will be close to:
