Q1: A body is said to move with Simple Harmonic Motion if its acceleration, isA
always directed away from the centre, the point of reference
B
proportional to the square of the distance from the point of reference
C
proportional to the distance from the point of reference and directed towards it
D
inversely proportion to the distance from the point of reference
E
none of these.
ANS:C - proportional to the distance from the point of reference and directed towards it Proportional to the distance from the point of reference and directed towards it. In other words, the acceleration of a body undergoing simple harmonic motion is directly proportional to its displacement from the equilibrium position and is directed towards the equilibrium position. So, the correct option is: Proportional to the distance from the point of reference and directed towards it. |
