Solution

Given: Mass on earth (me) = 5 kg, weight on earth (We) = 49 N,

acceleration due to gravity on moon (gm) = `9.8/6` m/s2 = 1.63 m/s2

To find: Mass (mm), weight (Wm) on moon

Formula: Wm = mmgm

Calculation: The mass of the object is independent of gravity and remains unchanged i.e., 5 kg.

From formula,

Wm = 5 × 1.63

∴ Wm = 8.15 N

On moon, the mass of the object is 5 kg and the weight is 8.15 N.
