Question

what is mass of an object whose wheight is 49N

Answer 1

Weight of an object = mass x gravitational acceleration

Assuming you're giving the weight of the object on earth,
49N =mass x 9.8m/s^2
mass = 49/9.8=5kg

Answer 2

Answer:

5.0 kg

Explanation:

Given :

Weight = 49N

Acceleration due to gravity = 9.7m/s²

To Find :

Mass of the body (m) = ?

Formula used :

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \implies \sf \: m = \dfrac{f}{g}$

On substituting :-

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \implies \sf \: m = \dfrac{49}{9.8}$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \implies \sf \: 5.0kg$

• Mass : It is a constant quantity of matter contained in body.

• Gravitation: Force exerted by earth. It is one of the weakest force of all.

• Velocity of is the vector quantity , quantifying the motion along straight line.

• the gravitational force of attraction between two given bodies is independent of nature of intervening medium.
