Question

The force of attraction due to a hollow spherical shell of mass M, radius R and uniform density, on a point mass m situated inside it is (A) (G m M/r2) (B) (G m M/R2) (C) zero (D) Data insufficient

Net resultant force at point P inside a hollow spherical shell will be zero because the attractive forces due to various parts of the shell cancel out each other. <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/physics/08bd3bd4e13abb85a1371c7200c43ee9-.png" /> i.e. mid F P text (net) mid= zero

Q. The force of attraction due to a hollow spherical shell of mass $M$ , radius $R$ and uniform density, on a point mass $m$ situated inside it is

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

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

zero

Net resultant force at point $P$ inside a hollow spherical shell will be zero because the attractive forces due to various parts of the shell cancel out each other.

i.e. $∣ F_{P} (net) ∣=$ zero
