the mass and weight of an object on Earth are 5 kg and 49 N respectively . What will be their values on the moon ? Assume that the acceleration due to gravity on the moon is 1/6th of that on the earth​

Answer»

\large\bf\underline {To \: find:-}

  • we NEED to find the weight of an object on MOON

\huge\bf\underline{Solution:-}

\bf\underline{\red{Given:-}}

  • mass of object = 5kg [on earth ]
  • Weight of object = 49N [ on earth ]

we know that,

✍︎ Weight = mass × ACCELERATION

As we know that, Acceleration of object is due to GRAVITY So,

weight = mass × acceleration due to gravity (G)

➳ 49 = 5 × g

➳ g = 49/5

➳ g = 9.8m/s²

Now,

● Acceleration on moon = 1/6 × 9.8

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀= 1.63m/s²

So,

⠀⠀⠀⠀⠀⠀☾⠀weight on moon :-

⪼ weight = mass × acceleration on moon

⪼ weight = 5 × 1.63

⪼ weight = 8.15N
