A charge of \( 5 \mathrm{C} \) is placed at the center of a circle of radius \( 10 \mathrm{~cm} \), as shown.
i) Calculate the work done in moving a charge of \( 2 \mathrm{C} \) from point \( \mathrm{A} \) to \( \mathrm{B} \) on the circumference of the circle.
ii) If the charge \( 2 C \) be first taken from \( A \) to \( P \) and then from \( P \) to \( B \), along which path work done will be more?
