A particle is moving an \(X\)-axis has potential energy \(U=2-20 x+5 x^2 \mathrm{~J}\) along \(X\)-axis. The particle is released at \(x=-3\). The maximum value of \(x\) will be (\(x\) is in metre and \(U\) is in joules)
- A \(5 \mathrm{~m}\)
- B \(3 m\)
- C \(7 \mathrm{~m}\)
- D \(8 \mathrm{~m}\)
Answer & Solution
Correct Answer
(C) \(7 \mathrm{~m}\)
Step-by-step Solution
Detailed explanation
Potential energy, \(U=2-20 x+5 x^2 J\) When particle gains whole of potential energy in the form of kinetic energy at \(x=-3 \mathrm{~m}\), then it will travel maximum distance till whole of its kinetic energy becomes zero.…
