MHT CET Physics question
The displacement-time graph of a particle executing SHM is shown.
Which of the following statement(s) is/are true? I. The force is zero at . II. The acceleration is maximum at . III. The velocity is maximum at . IV. The potential energy is equal to kinetic energy at
Answer: (B)
Solution
Reading the graph as a cosine curve, the particle is at the mean position at and (force zero, velocity maximum, so I and III are true) and at an extreme
