Consider a unigorm annular sphere of density p and internal radius 2m an external radius 4m. The graviational field strength at a point at a distance r=3 m, from the centre of shaper is : A. `-(32Gpip)/(9)`B. `-4Gpi`C. `-(32Gpip)/(9)`D. `(76)/(27)Gpip`

Answer» Correct Answer - D
`E=(GM)/(r^(2))`
`EG=(GM)/(9)`
Where M `rArrpx[(4pi)/(3)[3^(3)-2^(3)]]`
`rArr(pxx4pixx19)/(3)`
`rArr(Gpip76)/(27)`
