Question

if you are given 4 metal scales of same thickness of length 10cm,20cm,30cm and 40cm each respectively .they are placed with same length in air on the table.which of them vibrates with more frequently if same force is applied?​

Answer 1

Answer:

It is the 10cm scale

Explanation:

Because the scales are placed with the same length in air, scales with a longer length have more surface area in contact with the table. Thus, there is more area for longer scales to dissipate the vibrations on the scale.

So the scale with the shortest length will vibrate more with the same force when compared to longer scales
