Question

The weight of object on the surface of moon in is 60N. What will be its weight on Earth?

• A. 10N
• B. 36N
• C. 100 N
• D. 360N

Answer 1

Answer: (D)

360N

Answer 2

The weight of an object is given by the formula $W = m \times g$, where $m$ is the mass of the object and $g$ is the acceleration due to gravity. The mass of an object remains constant regardless of its location.

It is a known fact that the acceleration due to gravity on the Moon ($g_M$) is approximately one-sixth of the acceleration due to gravity on Earth ($g_E$). So, $g_M = \frac{1}{6} g_E$.

Given the weight of the object on the Moon ($W_M$) is 60 N. $W_M = m \times g_M = m \times \frac{1}{6} g_E = 60 \text{ N}$

We need to find the weight of the object on Earth ($W_E$). $W_E = m \times g_E$

From the equation for $W_M$: $m \times g_E = 6 \times 60 \text{ N}$ $m \times g_E = 360 \text{ N}$

Therefore, the weight of the object on Earth is 360 N.
