Question

A 30-kg object on Venus weighs 266.1 N. What is the value of gravity on Venus? A. 8.87 m/s2

B. 10.67 m/s2
C. 11.08 m/s2
D. 14.07 m/s2

Answer 1

The weight force on an object in a gravitational field is given by
`F = mg` where
`m` is the mass in kg and
`g` is the acceleration due to gravity at that place. Rearranging:

`g = (F)/(m) = (266.1)/(30) = 8.87 Nkg^&-1` or
`8.87ms^&-2`
Explanation: Venus is only slightly smaller than Earth, in both mass and radius, so this answer makes sense, when compared with the value of
`9.81 Nkg^&-1`at Earth's surface.
