The boy weighs 50.0 kg when he is 1R from the center of the Earth. To get his weight  5R away, we can use the formula:

W_{boy} = G * m1 * m2 / r^{2}

Where G, m1, and m2 are constants. By ratio and proportion:

W_{boy}  * ((5R)^{2}= 50.0 kg * 9.81 m/ * ((1R)^{2}

Canceling R on both sides and by computation:

W_{boy}= 19.6 N

SOVA2 [1]

Answer:

Answer is It was deduced from the rate at which it glimmers.

Refer below.

Explanation:

The X-ray source Cygnus X-1 has a mass of at least 11 solar masses and a diameter of only about one-quarter the diameter of the Earth. With such a small diameter it must be a compact object, and with such a large mass it can't be a white dwarf or a neutron star, so a black hole is the only possibility remaining. The diameter of Cygnus X-1 found:

It was deduced from the rate at which it glimmers.
