The weight of an object in the coal mine, sea level and at the top of the mountain are `W_(1),W_(2)` and `W_(3)` respectively, then

Options

A. `w_(1)=w_(2)=w_(3)`
B. `w_(1)lt w_(2)lt w_(3)`
C. `w_(1)gt w_(2)gt w_(3)`
D. `w_(1)lt w_(2)gt w_(3)`

Answer

D

Explanation

w = mg, hence the weight depends upon g.
`g_("mine")lt g_("sea level")` and `g_("mountain")lt g_("sea level")`
`therefore w_(1)lt w_(2)gt w_(3)`
