If the gravity decreases on the earth, we will be weightless and pressure will be less exerting on us and we will be able fly
Given :
- Mass of block = 3.5 kg
- Weight of Block = 3.5 kgf
- Volume of water displaced when body is fully immersed = 1000 cm³
Answer:
For calculating Upthrust on block we will have to first find out Volume of block :
↪Volume of block = Volume of water displaced
↪ Volume of block = 1000 cm³ = 0.001 m³
<h2>________________</h2>
Now, <u>we will calculate the Upthrust on block</u>:
↪ Upthrust on block = Volume of block * Density of water * g
↪ Upthrust on block = 0.001 * 1000 * g
↪ Upthrust on block = 1 kgf
