Answer to Problem 71A
Explanation of Solution
Given:
Density of wood,
Volume of the wood block,
Pool depth,
Formula Used:
The work done is given as,
Where,
The weight is given as,
Where,
Calculation:
To submerge the block extra force would require in downward direction.
Now, the net force is
For water,
So, work required
Conclusion:
Therefore, the work required is
