Identify the wrong statement from the following

Options

A. If the length of a spring is halved, the time period of each part becomes `(1)/(sqrt2)` times the original
B. The effective spring constant K of springs in parallel is given by `(1)/(K) = (1)/(K _(1)) + (1)/( K _(2)) + …`
C. The time period of a stiffer spring is less than that of a soft spring
D. The spring constant is inversely proportional to the spring length

Answer

B

Explanation

The wrong statement is the effective spring constant k of spring in parallel is given by
`(1)/(k) = (1)/(k _(1))+ (1)/( k _(2)) +...`
