Question

Hookes law gives relation between

• A. Extension in length of spring and force acting on it.
• B. Compression in length of spring and force acting on it.
• C. Both (a) and (b)
• D. None of these

Answer 1

The correct option is C Both (a) and (b)

$\begin{array}{c}\text{Hooke's low basically states}\\ \text{that the force(f) needed to}\\ \text{extend or compress a spring by}\\ \text{some distance}\left(x\right)\text{scales linearly}\\ \text{with respect to the distance}\end{array}$

$\text{that}[F_s=-kx]$

$\begin{array}{c}\text{Here}(-\sqrt{2})\text{sign represent that the force}\\ \text{vector of displacement lesctor are opposite}\\ \text{to each other.}\end{array}$

Hence option C is correct
