The effective capacity between a and b in the figure given is
find x.
\(\frac{43}{24} \mu F\)
\(\frac{24}{43} \mu F\)
\(\frac{43}{12} \mu F\)
\(\frac{12}{43} \mu F\)
\(\frac{1}{C_{eq}}=\frac{5}{6}+\frac{1}{8}+\frac{5}{6}=\frac{20+3+20}{24}\Rightarrow C_{eq}=\frac{24}{43}\mu F\)

Two charges \( +q \) and \( -q \) are placed at points \( A \) and \( B \) respectively which are at a distance \( 2L \) apart. \( C \) is the midpoint of \( AB \). The work done in moving a charge \( +Q \) along the semicircle CSD (\( W_1 \)) and along the line CBD (\( W_2 \)) are 
Find work done in bringing charge q = 3nC from infinity to point A as shown in the figure :
