Question

Mass of an object is 10 kg.

What is its weight on the earth?​

Answer 1

$\huge\star\mathfrak\red{{Answer:-}}$

Solution:

Mass, m = 10 kg

Acceleration due to gravity, g = 9.8 m s–2

W = m × g

W = 10 kg × 9.8 m s-2 = 98 N

Thus, the weight of the object is 98 N

Answer 2

Answer:

The weight of any body is the force with which earth attracts the body towards its centre. It is product of mass of body and accelration due to gravity (g) . And value of g varies along the earth from pole to equator .But in genral we take the value of g to be 9.81 m/s^2.

Hence , in your case weight of that body will be,

10kg *9.81m/s^2=98.1 N

Hence weight=98.1N...........
