A block of weight W is suspended from a spring balance. The lower surface of the block rests on a weighing mechine. The spring balance reads `W_(1)` and the weighing machine reads `W_(2)(W,W_(1),W_(2)` are in the same unit).

A spring balance reads W_(1) when a ball is suspended from it. A weighing machine reads W_(2) when a tank of liquid is kept on it. When the ball is immersed in the liquid, the spring balance reads W_(3) and the weighing machine reads W_(4) . Then, which of the following are not correct?

A 20 N metal block is suspended by a spring balance. A beaker containing some water is placed on a weighing machine which reads 40 N . The spring balance is now lowered so that the block gets immersed in the water. The spring balance now reads 16 N . The reading of the weighing machine will be.

A body is suspended from a spring balance kept in a satellite the reading of the balance is W_(1) when the satellite goes in an orbit of radius R and is W_(2) when it goes in an orbit of radius 2R
