An object suspended from a spring balance is immersed in water filled inside an overflow jar. The water displaced by the object is collected in an empty beaker placed below the spout of the overflow jar.
If the reading on the spring balance is `180" g"_(wt)`, then calculate the pressure exerted due to the immersion of object at the bottom of the container. Will there be any change in pressure at the lower, if the object is dropped into water ?
The height of the overflow jar upto the spout is 10 cm and the area of the lower face of the block is `4" cm"^(2)`.

Explanation

`"Pressure"=("Thrust")/("Area")`
When the object is suspended from the spring balance, the total weight is equal to weight of the liquid inside the container + loss of weight.
When the block is dropped, the pressure below the block is different. from that at other parts of the tank's bottom surface. Below the block the presssure would increase corresponding to the apparent weight of the block.
