Question
A metal wire of linear mass density of 9.8 gm is stretched with a tension of 10 kg-wt between two rigid supports 1 metre apart. The wire passes at its middle point between the poles of a per magnet and it vibrates in resonance when carrying an alternating current of frequency n. The frequency n of the alternating source is
Options
A.50 Hz
B.100 Hz
C.200 Hz
D.25 Hz
Solution
Frequency of oscillation n = 
=
× 102 = 
× 102 = 50Hz
=
× 102 = × 102 = 50HzCreate a free account to view solution
