Beenu Mathew · Answer

ans is (d) there is a relation u must remember ge=gp – Rw 2 cos 2 (phi) phi-latitude angle ge= g at that point gp/g(as given in q) – acc due to gravity at poles on solving u will get option (d) (remember ge=0...weightless...as given in the question) PLS APPROVE THANK YOU, HOPE THIS HELPS!!
