A particle of mass 3 gm moves along the x axis and is attracted towards the ongin by a force whose magnitude is numerically equal to 12 times the instantaneous displacement from the ongin The particle is also subjected to a damping force whose magnitude is 12 times the instantaneous speed If it is initially at rest at x 10 cm which one of the following equations gives the particle s position at a later time t 10 e cos 4t 10 40t e t 10 20t e 2 10 e 21 sin 4t
