Hint: To solve the question, first you need to think about what all the four motions in the option mean. After that, the fact that will help you reach the answer is that the string of the violin is in motion because the length of the string has been changed and thus, its elastic properties act and it gains some potential energy which sets it in motion.
Complete step by step answer:
As explained in the hint section, we first need to have a look at each of the options and understand what the motion means and the cause of the motion. Let us first start by talking about the oscillatory motion.
Oscillatory motion is a periodic motion which happens because of a restoring force, mostly a major contribution is due to the weight of the body. Every kind of body can show oscillatory motion, even rigid bodies can depict oscillatory motion, along with elastic bodies.
Non-periodic motion is a kind of motion which does not repeat itself, and even if it does, it does not do so in a fixed time period. This motion can also be depicted by all kinds of bodies.
Rectilinear motion is a type of motion when the body moves in a straight line, this kind of motion can also be depicted by any kind of body, but clearly, the string of violin doesn’t depict this motion.
Vibratory motion is a periodic motion in which the restoring force is due to the elastic properties of the body, hence, rigid bodies cannot depict the vibratory motion and only elastic bodies can. Any body or object that has mass and elasticity, can depict vibratory motion.
We can observe that the string of violin is in motion because of the potential energy that is induced in it by the elastic properties as its length was changed. Hence, this motion is clearly a vibratory motion.
Hence, the correct answer is the option (B)
Note: Many students tick the oscillatory motion as the correct answer which is wrong as even though vibratory motion is also oscillatory motion, but the cause behind the oscillatory motion is not the elastic property while it is so in the case of vibratory motion.
