The position of the two bridges from end A to divide the wire into three segments is 33.33 cm and 66.67 cm. (Option D).
How to calculate the length of the three segments of the sonometer?
The position of the two bridges from end A to divide the wire into three segments is calculated by applying the following formula.
The given parameters include;
total length of the sonometer wire = 100 cm
We will divide the total length of the sonometer wire by 3.
length of each segment = 100 cm / 3
length of each segment = 33.33 cm
Position of the first bridge = 33.33 cm
Position of the second bridge = 100 cm - 33.33 cm
= 66.67 cm
So the correct answer is option D.
