A 2 kg ball is dropped above the surface of Planet X. If the gravitational field strength at the surface of Planet X is 5 N/kg, what is the ball’s weight on the surface of Planet X?

Respuesta :

Given data:

* The mass of the ball is 2 kg.

* The gravitational field strength at the surface of planet X is 5 N/kg.

Solution:

The weight of the ball on the planet X is,

[tex]W=ma[/tex]

where m is the mass of ball, a is the gravitational field strength,

Substituting the known values,

[tex]\begin{gathered} W=2\times5 \\ W=10\text{ N} \end{gathered}[/tex]

Thus, the weight of the ball on the surface of planet X is 10 N.
