Question

an object weighs 98 n on earth. How much does it weigh on planet x where the acceleration due to gravity in 6 m/s^2

Answer 1

60 N because 98N=mg (here g= 9.8 on earth) thus mass can be calculated which is 98/9.8 = 10kg Now,new weight with g = 6m/s^2 =m×g' (here g' is new acceleration of the new planet) = 10×6=60N

Answer 2

The weight on planet x is 60 N

Step-by-step explanation:

It is given that,

Weight of an object on earth, W = 98 N

Value of acceleration due to gravity,
`g=9.8\ m/s^2`

Weight,
`W=mg`

`m=(W)/(g)=(98\ N)/(9.8\ m/s^2)=10\ kg`

Since, mass of an object remains same everywhere.

If the value of acceleration due to gravity on planet x is,
`a=6\ m/s^2`

So, weight on the planet x is,

`W=m* a`

`W=10\ kg* 6\ m/s^2`

W = 60 N

So, the weight on planet x is 60 N. Hence, this is the required solution.
