A) \[W\]
B) \[\frac{4W}{3}\]
C) \[\frac{5W}{3}\]
D) \[2W\]
Correct Answer: A
Solution :
Work done \[W=\frac{1}{2}CV\] \[\Rightarrow \] \[W=\frac{1}{2}C({{V}_{2}}-{{V}_{1}})\] \[\Rightarrow \] \[W=\frac{1}{2}C(10-5)=\frac{5}{2}C\] ...(i) Also, \[W=\frac{1}{2}C(5-10)\] \[\Rightarrow \] \[W=\frac{5}{2}C\] ...(ii) From Eqs. (i) and (ii), we get \[W=W\]
