If work W is done in blowing a bubble of radius R from a soap solution, then the work done in blowing a bubble of radius 2R from the same solution is
A
W/2
B
2W
C
4W
D
W
Text Solution
Verified by ExpertsThe correct answer is:
C
∴ ∴ 
(T is constant)
If radius becomes double then work done will become four times.
