For a point outside the spherical shell as shown below <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/physics/71b316fffa33d01dbc178ab68e9d24b8-.png" /> According to Newton's gravitational law, gravitational force on point mass m at P is | F P|=(G m M/d2)

Q. A point mass $m$ is placed outside a hollow spherical shell of mass $M$ and uniform density at a distance $d$ from centre of the sphere as shown in figure. Gravitational force on point mass $m$ at $P$ is

$\frac{G m M}{d ^{2}}$

zero

$\frac{2 Gim M}{d ^{2}}$

Data insufficient

For a point outside the spherical shell as shown below

According to Newton's gravitational law, gravitational force on point mass $m$ at $P$ is
$∣ F_{P} ∣ = \frac{G m M}{d ^{2}}$
