Answer & Solution

Correct Answer

(C) 72 s

Step-by-step Solution

Detailed explanation

The figure below represents the three point charges forming equilateral triangle. The energy system of three charges, U=3kq1q2r U=3×k2×10-3×2×10-312 U=24k×10-6 J When one charge moves to the midpoint of the line joining the other two charges, The…
