Question

An object weighs 10 N when measured on the surface of the earth. What would be its weight when measured

on the surface of the moon? ncert book class 9 in physics
​

Answer 1

Given :-

Mass of the object on earth = 10 N

To Find :-

The weight of the object on the surface of moon.

Analysis :-

Here we are given with the mass of the object on the surface on the earth.

In order to find the weight of the object on the surface of the moon substitute the given values such that the weight of the moon is one sixth of that on the moon.

Solution :-

We know that,

• m = Mass
• g = Gravity

Using the formula,

$\underline{\boxed{\sf Weight \ on \ moon=\dfrac{1}{6} \times Weight \ on \ earth}}$

Given that,

Weight on earth (m) = 10 N

Substituting their values,

⇒ 1/6 × 10

⇒ 10/6

⇒ 1.67 N

Therefore, the weight of the object on moon is 1.67 N.

Answer 2

Answer:

Given :-

• An object weights 10 N when measured on the surface of the earth.

To Find :-

• What is the weight of an object when its measured on the surface of the moon.

Formula Used :-

We know that,

❖ Weight on the moon = 1 ÷ 6 × Weight on earth ❖

Solution :-

Given :

• Weight on the earth = 10 N

According to the question by using the formula we get,

↣ Weight on the moon = 1 ÷ 6 × 10

➠ Weight on the moon = 1.67 N

∴ The weight of an object when its measured on the surface of the moon is 1.67 N .
