AP EAMCET · PHYSICS · Work Power Energy
A particle slides down along an inclined plane \(A C\). If the plane is frictionless, kinetic energy of particle at \(C\) is
- A \(m g y\)
- B \(m g x\)
- C \(m g\left(\frac{y}{\sin \theta}\right)\)
- D \(m g\left(\frac{y}{\cos \theta}\right)\)
Answer & Solution
Correct Answer
(A) \(m g y\)
Step-by-step Solution
Detailed explanation
Let the mass of the particle be \(m\). If the particle slides from height \(y\) under the action of gravity, the velocity acquired by the particle is given by, \(v=\sqrt{2 g y}\) Hence, kinetic energy, \(\mathrm{KE}=\frac{1}{2} m v^2\)…
