What will be the weight of an object on the surface of the earth whose mass is 6 kg on the moon’s surface?

The correct answer is 60 N.

Step 1: Understand the difference between mass and weight
Mass is an intrinsic property of an object that measures the amount of matter contained within it. It remains constant regardless of the object's location in the universe. Therefore, if the mass of an object on the surface of the Moon is 6 kg, its mass on the surface of the Earth is also 6 kg.

Step 2: Use the weight formula
Weight is the gravitational force exerted on an object. It is calculated using the formula:

$W=m\times g$

where:

$W$ represents the weight of the object,

$m$ represents the mass of the object ($m=6\text{kg}$), and

$g$ represents the acceleration due to gravity on Earth ($g=10{\text{m/s}}^2$).

Step 3: Calculate the weight on Earth
Substitute the values of mass and gravity into the equation:

$W=6\text{kg}\times 10{\text{m/s}}^2$

$W=60\text{N}$

Therefore, the weight of the object on the surface of the Earth is 60 N.
