MHT CET Physics question
A sonometer wire resonants with 4 antinodes between two bridges for a given tuning fork, when 1 kg mass is suspended from the wire. Using same fork, when mass M is suspended, the wire resonates producing 2 antinodes between the two bridges (distance between two bridges is as before). The value of M is [MHT-CET 2021]
Answer: (C)
Solution
Loops , so gives kg; 2.5, 3.5 and 1 kg do not satisfy this. Hence the correct option is (c).
