Question

The weight of the body at a certain place is 30N The acceleration due to gravity at that point is 10m/s² . Find out the mass and weight of the object at the place where acceleration due to gravity is zero ​

Answer 1

if acceleration is 0 than weight is 0 and mass
is remaining constant 3 kg

Answer 2

Given:

Weight of the body $=30N$

Acceleration due to gravity $=10m/s^{2}$

To find:

The mass and weight of the object where acceleration due to gravity is 0.

Solution:

We have been given that the weight of a body at a certain place is $30N$ and the acceleration due to gravity at that point is $10m/s^{2}$.

We know,

Weight of a body is given by $W=mg$

We have,   $W=10N$  $;$  $g=10m/s^{2}$

$30=m(10)$

$m=3kg$

The mass of a body is a definite value that remains constant and does not change with the change in height or depth to which the mass be taken.

According to the question, a point where acceleration due to gravity is 0.

$g=0m/s^{2}$

Hence, the weight of the mass $m=3kg$ at this point will be

$W=mg$

$W=3(0)$

$W=0N$

Final answer:

Hence, the mass of the body is 3 kg and its weight at a point where acceleration due to gravity is 0 is 0 N.
