Question

When a spring balance, showing a reading of 100 divisions at equator for a body, is taken to the poles, then find the reading shown by it
(Take `(g_(p))/(g_(E))=1.01`)

Answer 1

Let `w_(E) "and" w(p)` be the readings at equator and at poles, respectively.
`w_(E) = mg_(E), w_(p) = mg_(p) rArr (w_(E))/(w_(p))=(100)/(w_(p))=(mg_(E))/(mg_(p))`
`rArr w_(p) = 100((g_(p))/(g_(E))) = 100 xx 1.01 = 101`
