Mass of an object is 20 kg. What is its weight on the earth?

Answer 1

★$\textbf{Question:-}$

»Mass of an object is 20 kg. What is its weight on the earth?

★$\textbf{To know:-}$

• Weight-Weight of an object is the force with which the object is attracted to the earth.
• Also, we have the equation => W = m × g where 'm' is the mass of the object and 'g' is the acceleration due to gravity.
• The SI unit of weight is same as that of force which is Newton (N) as weight of a particular object is the force with which it is attracted towards the earth.

★$\textbf{To find:-}$

=>Weight of the object on Earth

★$\textbf{Given:-}$

• Mass of the object(m) = 20 kg
• Acceleration(g) = 9.8 m/s

★$\textbf{Solution:-}$

Weight of the object on earth = Mass(m) × Acceleration due to gravity(g)

i.e.,

=>W = m × g

Putting the values,

=>W = 20 Kg × 9.8 m/s

=>W = 196 N

★$\textbf{Answer:-}$

Therefore,the weight of the object on earth is 196 Newton (N).
