A particle of mass \( 100 \mathrm{gm} \) and charge \( 2 \mu \mathrm{C} \) is released from a distance of \( 50 \mathrm{~cm} \) from a fixed charge of \( 5 \mu \mathrm{C} \). Find the speed of the particle when its
\( \mathrm{P} \) distance from the fixed charge becomes \( 3 \mathrm{~m} \). Neglect any other force.

W
(A) \( -1.73 \mathrm{~m} / \mathrm{s} \)
(B) \( 2.73 \mathrm{~m} / \mathrm{s} \)
(C) \( -2.73 \mathrm{~m} / \mathrm{s} \)
(D) \( 1.73 \mathrm{~m} / \mathrm{s} \).
