Q. 2

# Inside a uniform spherical shell

A. The gravitational potential is zero

B. The gravitational field is zero

C. The gravitational potential is same everywhere

D. The gravitational field is same everywhere.

Answer :

Inside a shell, the gravitational field is zero, while gravitational potential exists and is constant. So, (a) is wrong and (b) is correct. As the potential is constant, (c) is true. The value of gravitational field inside a sphere is zero everywhere. Hence (d) is true.

A small block of super dense material has a mass of 3 × 10^{24} kg. It is situated at a height h (much smaller than the earth’s radius) from where it falls on the earth’s surface. Find its speed when its height from the earth’s surface has reduced to h/2. The mass of the earth is 6 × 10^{24} kg.
