Which of the following is/are false regarding Hooke's law? I) If the force exerted by the spring on the object connected to the end of a spring obeys this law, the force is in equilibrium. It is proportional to the absolute value of the displacement measured from its position. II) Springs obeying this law are attached to the objects to which they are attached, due to the displacement measured from the equilibrium position. They exert a force proportional to the negative. III) The spring force obeying this law is proportional to the spring constant, which is a property of the spring. a) I b) II c) I and III d) II and III e) III
Simple harmonic motion
Simple harmonic motion is a type of periodic motion in which an object undergoes oscillatory motion. The restoring force exerted by the object exhibiting SHM is proportional to the displacement from the equilibrium position. The force is directed towards the mean position. We see many examples of SHM around us, common ones are the motion of a pendulum, spring and vibration of strings in musical instruments, and so on.
Simple Pendulum
A simple pendulum comprises a heavy mass (called bob) attached to one end of the weightless and flexible string.
Oscillation
In Physics, oscillation means a repetitive motion that happens in a variation with respect to time. There is usually a central value, where the object would be at rest. Additionally, there are two or more positions between which the repetitive motion takes place. In mathematics, oscillations can also be described as vibrations. The most common examples of oscillation that is seen in daily lives include the alternating current (AC) or the motion of a moving pendulum.
