Question

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

Answer 1

Answer:

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.

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. $Weight= Mass\times Acceleration \ due \ to \ gravity$

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

On substituting the values,

Weight = $10 kg\times 9.8 m/s^2$

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

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

Weight = 98 N
