A positive charge \( Q=50 \mu C \) is located in the xy plane at a point having position vector \( \overrightarrow{\bar{l}}_{0}=(2 \hat{i}+3 \hat{\mathbf{j}}) \mathrm{m} \)
where \( \hat{i} \) and \( \hat{j} \) are unit vectors in the positive directions of \( X \) and \( Y \) axis respectively. Find:
Work done by external agent in transporting a charge \( q=10 \mu \mathrm{C} \) from \( (8 \mathrm{~m}, 6 \mathrm{~m}) \) to the point \( (4 \mathrm{~m}, 3 \mathrm{~m}) \).
