MCQ
According to Hook’s law force is proportional to
- A$\frac{1}{x}$
- B$\frac{1}{{{x^2}}}$
- ✓$x$
- D${x^2}$
✓
Answer
Correct option: C.
$x$
c
(c)
(c)
According to Hooke's law, within elastic limit for elastic material, material act as a spring, which reforms its shape after we deform it by some external force. Hence, a restoring force occurs
$\therefore F =- kx \quad k =$ spring constant
$\therefore F \propto x$
