Which of the statement below is correct about Hooke's Law?

• Hooke's Law state that the length of the spring is directly proportional to the Force applied to the spring if the elastic limit is not exceeded.

• Hooke's Law state that the length of the spring is directly proportional to the Pressure applied to the spring if the elastic limit is not exceeded.

• Hooke's Law state that the Extension of the spring is directly proportional to the Force applied to the spring if the elastic limit is not exceeded.

• Hooke's Law state that the extension of the spring is directly proportional to the Pressure applied to the spring if the elastic limit is not exceeded.
