Question

Which of the following graphs represents the gravitational field intensity due to solid sphere of radius $R$ ?

• A. (i) only
• B. (ii) only
• C. (iii) only
• D. (iv) only

Answer 1

Answer: (C)

Let, $a$ solid sphere of radius $R$, mass $M$ and centre at $O$
$I=\frac{GMr}{R^3},(r<R)$
if $r>R$
$I=\frac{GM}{r^2}$
