MHT CET 2026 Physics question
A sonometer wire resonates with 4 antinodes between the 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 the bridges as before) The value of M is
Answer: (C)
Solution
With loops (antinodes) between the bridges of separation , the frequency is , where for a suspended mass . Since , and are the same in both cases, is constant, so is constant:
