The displacement time graph of a particle executing S.H.M. is given in figure :(sketch is schematic and not to scale) Which of the following statement is/are true for this motion? (A) The force is zero at
(B) The acceleration is maximum at t=T
(C) The speed is maximum at
(D) The P.E. is equal to K.E. of the oscillation at
Option: 1 (A) and (D)
Option: 2 (A), (B) and (C)
Option: 3 (B), (C) and (D)
Option: 4 (A), (B) and (D)
From graph equation of SHM
A)
At , the particle is at the mean position.
So The force is zero at
B)
at T particle is at the extreme position so acceleration is maximum
C)
The speed is maximum at
because at particle is at the mean position.
D)
So A, B and C are correct
