At high altitude, a body explodes which is at rest into two equal fragments with one fragment receiving horizontal velocity of \(10 \mathrm{~ms}^{-1}\). Time taken by the two radius vectors connecting point of explosion to fragments to make \(90^{\circ}\) is
- A \(10 \mathrm{~s}\)
- B \(4 \mathrm{~s}\)
- C \(2 \mathrm{~s}\)
- D \(1 \mathrm{~s}\)
Answer & Solution
Correct Answer
(D) \(1 \mathrm{~s}\)
Step-by-step Solution
Detailed explanation
The given situation is shown in the following figure. According to question, angle between two radius vector is \(90^{\circ}\). \(\text {i.e., } \theta+\theta=90^{\circ} \Rightarrow \theta=45^{\circ}\) \(\therefore\) Time taken by the two radius vectors connecting of explosion…
