Black hole:A black hole is a place in space where gravity pulls so much that even light can not get out. The gravity is so strong because matter has been squeezed into a tiny space. From Newton’s universal law of gravitation,The photons have no mass. From Einstein’s mass energy equivalence relation E = mc2 According to quantum theory of radiation, E = hv∴ m = h/cλPutting in the expression of Newton’s law of gravitation, Force acting on the light particlesBecause no light can get out, people can't see black holes. They are invisible. Space telescopes with special tools can help find black holes. A beam of light just grazing the edge of the sun also bend a little. This may be observed during total solar eclipse. The position of a star will appears closer to the sun. Black holes can be big or small. Scientists think the smallest black holes are as small as just one atom. These black holes are very tiny but have the extremely high density. Another kind of black hole is called "stellar." Its mass can be up to 20 times more than the mass of the sun. There may be many, many stellar mass black holes in milky Way. The largest black holes are called "super massive." These black holes have masses those are more than 1 million suns together. Scientists have found proof that every large galaxy contains a super massive black hole at its center. The super massive black hole at the center of the Milky Way galaxy is called Sagittarius A. It has a mass equal to about 4 million suns and would fit inside a very large ball that could hold a few million Earths. A black hole can not be seen because strong gravity pulls all of the light into the middle of the black hole. But scientists can see how the strong gravity affects the stars and gas around the black hole. If a black hole the same mass as the sun replace the sun, Earth and the other planets will orbit the black hole as they orbit the sun now.What will happen to the earth and other planets if a black hole of same mass as the sun replaces the sun?

Gravitational acceleration on the surface of a planet iswhere g is the gravitational acceleration on the surface of the earth. The average mass density of the planet is 2/3times that of the earth. If the escape speed on the surface of the earth is taken to be 11 kms-1, the escape speed on the surface of the planet in kms-1will be[jee 2010] Correct answer is '3'. Can you explain this answer?
