Question

The two ends of a spring are displaced along the length of the spring. All the displacements have equal magnitudes. In which case or cases, the tension or compression in the spring will have a maximum magnitude?
$\left(i\right)$ The right end is displaced towards the right and the left end towards left.
$\left(ii\right)$ Both ends are displaced towards the right
$\left(iii\right)$ Both ends are displaced towards left
$\left(iv\right)$ The right end is displaced towards left and the left end towards the right

• A. $\left(i\right)$ and $\left(iv\right)$
• B. only $\left(ii\right)$
• C. $\left(ii\right)$ and $\left(iii\right)$
• D. only $\left(iii\right)$

Answer 1

The correct option is A $\left(i\right)$ and $\left(iv\right)$


Compression is maximum if A moves right, B moves left.
Tension is maximum if A moves left, B moves right.
