Question

If a rock weighs 75.0 n on earth, what would it weigh at the surface of venus?

Answer 1

Its weight will be 75g'/9.8 where g' is the acceleration due to gravity of venus.

Answer 2

Answer:

Weight on Venus is 66.5 N    

Explanation:

It is given that,

The weight of rock on the surface of earth is 75 N. We have to find its weight on the surface of Venus.

We know that, weight of an object on the surface of earth is given by :

W = m g

m is the mass of rock

and g = 10 m/s² (on earth)

$m=\dfrac{W}{g}$

$m=\dfrac{75\ N}{10\ m/s^2}$

m = 7.5 Kg

The value of g on the surface of Venus is equal to, g' = 8.87 m/s²

The weight of rock on Venus is, W' = m g'

W' = 7.5 kg × 8.87 m/s²

W' = 66.5 N

Hence, this is the required solution.
