SATHEE: Gravitation Question 10

Gravitation Question 10

Question: The mass and diameter of a planet have twice the value of the corresponding parameters of earth. Acceleration due to gravity on the surface of the planet is[NCERT 1971; Pb. PMT 2000]

Options:

A) $[9.8, m / \sec^{2}]$

B) $[4.9, m / \sec^{2}]$

C) $[980, m / \sec^{2}]$

D) $[19.6, m / \sec^{2}]$

Show Answer

Answer:

Correct Answer: B

Solution:

$[\frac{g^{'}}{g} = \frac{M^{'}}{M} {(\frac{R}{R^{'}})}^{2} = (\frac{2 M}{M}) {(\frac{R}{2 R})}^{2} = \frac{1}{2}]$ Þ $[g^{'} = \frac{g}{2} = \frac{9.8}{2} = 4.9 m / s^{2}]$
