The length of a rubber cord is

{l_1}

when the work done on it is 4J and

{l_2}

when he work done on it is 9J. The length of the cord, when work done is 16J is

View answer and explanation

Correct option: D

2{l_2} - {l_1}

Option D (

2{l_2} - {l_1}

) is correct because it represents the length of the cord when the work done is 16J, derived from the relationship between work and extension.
