Gravitation Question 2
Question 2 - 24 January - Shift 2
Given below are two statements:
Statement I: Acceleration due to earth’s gravity decreases as you go ‘up’ or ‘down’ from earth’s surface.
Statement II: Acceleration due to earth’s gravity is same at a height ’ $h$ ’ and depth ’d’ from earth’s surface, if $h=d$.
In the light of above statements, choose the most appropriate answer form the options given below
(1) Statement I is incorrect but statement II is correct
(2) Both Statement I and Statement II are incorrect
(3) Statement I is correct but statement II is incorrect
(4) Both Statement I and II are correct
Show Answer
Answer: (3)
Solution:
Formula: Effect of Altitude, Effect of depth
$g^{\prime}=\frac{g}{(1+\frac{h}{R})^{2}}$
$g^{\prime}=g{1-\frac{d}{R}}$
Statement I is correct \& Statement II is incorrect
