**A spring has time period T. It is cut into n equal parts. The time period of each part will be **

### Options

(a) T√n

(b) T/√n

(c) nT

(d) T

### Correct Answer:

T/√n

### Explanation:

Whe a spring of constant K is cut into n equal parts, each part has a spring constant = nK

T = 2π √(m/K)

T’ = 2π √(m/nK) = (1/√n).2π √(m/K)

T’ = T/√n.
