Question

Which one of the following graphs represents correctly the variation of the gravitational field $\left(E\right)$ with the distance from$\left(r\right)$ the centre of a spherical shell of mass $M$ and radius a?

• A. diagram
• B. diagram
• C. diagram
• D. diagram

Answer 1

The correct option is C diagram

Formula used: $E=\frac{Gm}{(R{)}^2}$

Gravitational field due to spherical shell varies with distance.

$\left(i\right):r>R$
$E=0$
$\left(ii\right):r=R$
$E=\frac{Gm}{R^2}$
$\left(iii\right):r<R$
$E=\frac{Gm}{r^2}$
Final Answer: (d)
