Question

*एकक वस्तुमानांच्या दोन वस्तूमधील अंतर एक एकक असल्यास त्यांच्यातील गुरुत्वाकर्षण बल हे ----------- इतके असते.*
for English
* If the distance between two objects of unit mass is one unit, then the force of gravity between them is -----------. *
​

Answer 1

ANSWER

We know that According to the law of gravitation, the force between any two objects of mass M and m is directly proportional to their masses and inversely proportional to the square of the distance between them.

F=G

r

2

Mm

So, if Distance is halved, i.e new r=

2

r

So, New F=G

2

2

r

2

Mm

⇒F=4G

r

2

Mm

So, Force of gravitation increases by 4 times when distance reduced by half

Answer 2

Answer:

2 m
