Question

47. Find the weight of a stone on the surface of Earth if its mass is 20kg (g=9.8m/s^2)

Answer 1

Answer:

nothing

Explanation:

given: mass= 20 kg

g= 9.8m/s^2

we know, W=m×g

=20 × 9.8

= 196

therefore weight of the stone is 196 N

Answer 2

Given,

Mass of a stone on the surface of earth = 20 kg

Acceleration due to gravity = g = 9.8m/s^2

To find,

Weight of the stone.

Solution,

We can simply solve this numerical problem by using the following process:

Mathematically,

Weight of any object (W)

Weight of any object (W) = mass of the object (m) x acceleration due to gravity (g)

Now,

Weight of the stone

= mass of the stone (m) x acceleration due to gravity (g)

= 20 Kg x 9.8m/s^2

= 196 N

Hence, the weight of the stone is equal to 196 N.
