Question: A central particle M is surrounded by a square array of other particles, separated by either distance d or distance d/2 along the perimeter of the square. The magnitude of the gravitational force on the central particle due to the other particles is
Options:
A) $ [\frac{9GMm}{d^{2}}] $
B)$ [\frac{5GMm}{d^{2}}] $
C) $ [\frac{3GMm}{d^{2}}] $
D)$ [\frac{GMm}{d^{2}}] $
Show Answer
Answer:
Correct Answer: C
Solution:
- $ [F=\frac{GM\left( 3m \right)}{d^{2}}=\frac{3GMm}{d^{2}}] $ .
