Question 8

Which of the following figure shows the correct placement of a block along a scale for measuring its length?

(a)

(b)

(c)

(d)

Answer 1

1. The placement of the block in option C is correct.
2. In option ( A) block position is before zero hence A is the incorrect option
3. In option ( B) block position is not correctly placed on the scale hence B is the incorrect option

We can see that the placement of the block in other options is out of the marking the f 15 cm scale. So there will be an error in measuring the length of the block. Only option (c) has the placement which is inside the marking of scale.

Hence The placement of the block in option C is correct.
