Question

Statement I : A body becomes weightless at the centre of earth.
Statement II : As the distance from centre of earth decreases, acceleration due to gravity increases.

• A. If both statement I and statement II are true and statement II is the correct explanation of statement I
• B. If both statement I and statement II are true but statement II is not the correct explanation of statement I
• C. If statement I is true but statement II is false
• D. If both statement I and statement II are false

Answer 1

Answer: (C)

As the distance from centre of earth decreases, acceleration due to gravity decreases and at the centre of earth it becomes zero.
$g' = g(1 - \frac{d}{R})$. if $d = R$ then $g' = 0$
