Question

What is the mass of an object whose weight is 50 n?

Answer 1

In physics the standard unit of weightis Newton, and the standard unit ofmass is kilogram. On Earth, a 1 kg object weighs 9.8 N, so to find theweight of an object in N simply multiply the mass by 9.8 N. Or, to findthe mass in kg, divide the weight by 9.8 N.

so it is mass=50/9.8
=5.10kg

Answer 2

The mass of the object is 5.1 kg (approx)

Given:
Weight of the object $= 50N$

To find:

The mass of the object.

Solution:
The mass of an object is its constant intrinsic property which does not change with change in altitude or depth of the position where the object is placed. Mass is denoted by $M$ and its SI unit is kilogram.

Whereas, weight of an object is not a constant quantity as it depends on the position of an object and changes its value with change in acceleration due to gravity due to altitude or depth.

                     $W=mg$

Where, $m$ is the mass of the object and the SI unit of weight is Newton.

Now,

According to the question, we have

$W=50N$

We know, $g=9.8m/s^{2}$

$W=mg$

Hence,

$mg=50$

$m$ × $9.8=50$

$m=5.102kg$

Final answer:

Hence, the mass of the object is 5.1 kg (approx).
