Question

A particle is in linear simple harmonic motion between two extreme pointsA and B, 10 cm apart (see fig). If the direction from A to B is taken as positive direction, what are signs of displacement x, velocity V and acceleration a, when the particle is at A  

                                                

Solution

Correct option is

Displacement x = – 5 cm, i.e. x = – ve. Velocity at extreme points is zero. Acceleration is opposite to displacement. The

 a = +ve.
