Question

The distance between two objects is 10m, the two objects attract each other as 20N. If the mass of the 1st object is 2kg, what is the mass of the 2nd object?

A)1.499×10¹³

B) 1.499×10¹²

C)1.62×10¹³

D)1.3×10¹³

give answer with explanation​

Answer 1

$\huge\star\underline\mathfrak\red{Answer:-}$

The gravitational force between two objects is inversely proportional to the square of distance between them.

So, if the distance between two objects is doubled, then the gravitational force becomes

2×2

1

.

That is, 1/4.

Therefore, if the distance between two masses be doubled, then the force between will becomes 1/4.
