Question

The weight of a body on moon in 600 N. The mass of the body  in kg is-
1. 360
2. 362
3. 365
4. 367

Answer 1

Correct Answer - Option 4 : 367

Concept:

Weight is defined as a measure of the gravitational force on that body at that place.

Weight = Mass x Surface Gravity.

W = mg

• Surface Gravity on Moon = \({1\over6}{Surface \ Gravity\ on\ Earth}\)
• Surface Gravity on Earth, g = 9.8 m/s2.

Mass doesn’t change according to location.

• The mass of a body is the same on Earth and Moon.
• Mass is the measure of the amount of matter in a body.
• The SI unit of mass is the kilogram (kg).
• Mass is a scalar quantity, and It has magnitude.
• The mass of a body is not dependent on time.
• Mass is not dependent on gravity.
• Mass can never be zero.

Calculation:

Given:W_m = 600 N

W_e = W_m × 6

W_e = 600 × 6

W_e = 3600

Using, W = mg

3600 = m × 9.81

m = 366.97 kg 

m ≈ 377 kg
