Spring Force

A block of mass m is hanging from the ceiling by a spring whose spring constant is k. Now the spring is pulled further down by x units.
Find the spring force acting on the block at that instant?
Two blocks of unequal masses are tied by a spring. The blocks are pulled stretching the spring slightly and the system is released on a frictionless horizontal platform. Are the forces due to the spring on the two blocks equal and opposite? If yes, is it an example of Newton's third law?

A spring balance A shows a reading of 2 kg, when an aluminium block is suspended from it. Another balance B shows a reading of 5 kg, when a beaker full of liquid is placed in its pan. The two balances are arranged such that the Al – block is completely immersed inside the liquid as shown in the figure. Then
The reading of the balance B will be less than 5 kg
The reading of the balance A will be less than 2 kg. and that of B will be more than 5 kg
The reading of balance A will be 2 kg. and that of B will be 5 kg.
The reading of the balance A will be more than 2 kg
