A uniform spring of spring constant k is cut into two pieces whose lengths are in the ratio 1 : 2. The ratio of frequencies of oscillations in the vertical direction when mass m each is suspended from the smaller and the larger pieces of the spring is –
A
21
B
2
C
21
D
2
Answer
21
Explanation
Solution
Also ℓ1ℓ2 = 2
Solving k1 = , k2 = 3k
n1 = 2π1 2π1
