A body of mass \(m\) is suspended to an ideal spring of force constant \(k\). The expected change in the position of the body due to an additional force \(F\) acting vertically downwards is
- A \(\frac{3 F}{2 k}\)
- B \(\frac{2 F}{k}\)
- C \(\frac{5 F}{2 k}\)
- D \(\frac{4 F}{k}\)
Answer & Solution
Correct Answer
(B) \(\frac{2 F}{k}\)
Step-by-step Solution
Detailed explanation
Let the change in position of the body due to additional force is \(x\). So, \(\begin{aligned} & F=\frac{1}{2} k x \\ & x=\frac{2 F}{k} \end{aligned}\) \(\therefore \quad x=\frac{2 F}{k}\)
