Question

What is the weight in newtons of a 10 kg mass on the earth's
surface?

Answer 1

98 kg

Mass is given as 10 kg. Therefore, Weight = 10 kg * 9.8 m/s^2. Weight = 98 kg.m/s^2. = 98 Newtons.

Answer 2

The weight in newtons of a 10 kg mass on the earth's surface is 98 N.

Step-by-step explanation:

Every object on the Earth experiences an acceleration of
`9.8 m/s^2` due to gravity. From the given,

Mass of the object = 10 kg

To calculate the weight of the object we have to multiply the given mass of the object by the acceleration due to gravity.

i.e.
`Weight= Mass* Acceleration \ due \ to \ gravity`

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

On substituting the values,

Weight =
`10 kg* 9.8 m/s^2`

`(1 N = 1 kg. m/s^2)`

`\bold{\Rightarrow 98 \ kg.m/s^2\Rightarrow 98 N}`

Weight = 98 N
