STANDARD Physics Work and Energy MCQ Question
Type: MCQ-numerical-Hard
If W₁ be the work to be done to form a bubble of volume V from a given solution. The work required to be done to form a bubble of volume 2 V is
A
4²/³ W₁
B
4¹/³ W₁
C
2¹/² W₁
D
2³/² W₁
Correct Answer
Option B
Detailed Explanation
The work done is proportional to the surface area, which is proportional to the volume raised to the power of 2/3. Therefore, the work required for volume 2V is 4¹/³ times W₁.
