Question

While establishing the relation between the loss in weight of a solid when immersed in tap

water and strongly salty water, an iron ball is hanged from the hook of a spring balance. It is first

kept in air, then fully immersed in tap water and then immersed in salty water. The reading of the

spring balance will be

(a) minimum in air (b) minimum when immersed in tap water (c)

minimum when immersed in salty water (d) equal in all the cases.​

Answer 1

Answer:

d d option is correct because mass is never changing it is a type of intrinsic property of the matter means it is the property that is inside the matter that the metric you bye the option is correct because mass is never change if we go from one place to another or taking it from one source to another source

Answer 2

Answer:

(c) minimum when immersed in salty water

Explanation:

When the ball is immersed in the tap water it experiences an buoyant force which is equal to the tap water displaced by it so, the net force of weight becomes lesser.

When it is immersed in salty water it experiences more buoyant force as the weight of salt water is more because of of salt water has more density than the tap water so, the net of force of weight is least here.

In air, it does not experiences any buoyant force of water which makes it's net force most from all of these cases.
