Question

If 10 meters of a uniform rod weighs 18Kg, Then the weight of 5 metres of
the rod is

Answer 1

As per the data given in the question,

In the above question, it is given that,

Given that 10 meters of a uniform rod weigh 18Kg.

 Here we have to find the weight of 5 metres of

the rod.

We have to know the weight of 1metre and then know the value of 5metre.

Thus, the weight of 1 metre is,

$=\frac{18}{10} \\=1.8kg$

Therefore the weight of 5 metre rod is,

$=5\times 1.8\\=9kg$

Hence the weight of a 5metre rod is 9kg.

Answer 2

Here it is given that the weight of 10 meter rod is 18 Kg

We will first find out the weight of 1 kg rod

10 m rod = 18 kg

1 m rod = 18 / 10 kg

             = 1.8 kg

Now, we will calculate the weight of 5 m rod

Weight of 5 m rod = 5 × 1.8

                              = 9 kg

Hence, the weight of 5 m long rod will be 9 kg
