A particle is in linear simple harmonic motion between two points A and B, 10 cm apart Take the direction from A to B as the positive direction and give the signs of velocity, acceleration and force on the particle when it is
(i) at the end A
(ii) at the end B.
(iii) at the mid-point of AB going towards A
(iv) at 2 cm away from B going towards A
(v) at 3 cm away from A going towards B.
(vi) at 4 cm away from B going towards A
