Question

. ਇੱਕ ਵਸਤੂ ਦਾ ਹਵਾ ਵਿੱਚ ਭਾਰ 10 N ਹੈ । ਪਾਣੀ ਵਿਚ ਡੁਬੋਏ ਜਾਣ ਤੋਂ ਬਾਅਦ ਇਸ ਦਾ ਭਾਰ 8 N ਰਹਿ ਜਾਂਦਾ ਹੈ । ਇਸ ਦੁਆਰਾ ਵਿਸਥਾਪਿਤ ਕੀਤੇ ਪਾਣੀ ਦਾ ਭਾਰ ਹੋਵੇਗਾ। An object weighs 10N in air . When immersed in water , it weighs only 8 N. The weight of the liquid displaced by the object will be: हवा में किसी वस्तु का वजन 10 N है। पानी में डूबे रहने के बाद इसका वजन 8 N रहता है। यह इसके द्वारा विस्थापित पानी का वजन होगा । *

8 N

10 N

12 N

2 N

​

Answer 1

Given : An object weighs 10N in air . When immersed in water , it weighs only 8 N.

To Find : The weight of the liquid displaced by the object will be:

Solution:

When an object is fully immersed in water

The object suffers an apparent weight loss equal to the weight of the fluid displaced.

apparent weight of the object = Weight of object - apparent weight loss

=> apparent weight of the object = Weight of object -  weight of the fluid displaced.

Weight of object = Weight in Air = 10N

Weight in water =  apparent weight of the object  = 8N

=> 8  = 10 - weight of the fluid

=> weight of the fluid  = 2N

The weight of the liquid displaced by the object will be 2N

विस्थापित पानी का वजन 2N होगा
