Question

A block of mass 3.5 kg displaces 1000 cm ^3 of water when fully immersed inside. The upthrust on body will be what​.

Answer 1

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

________________

Now, we will calculate the Upthrust on block:

↪ Upthrust on block = Volume of block * Density of water * g

↪ Upthrust on block = 0.001 * 1000 * g

↪ Upthrust on block = 1 kgf
