two point charges one at x=3m and other at x=-3m.

Question

two point charges one at x=3m and other at x=-3m.A third charge of mass m and charge -Q is released from rest at y=4m. Find the speed of the particle when it reaches the origin

Kapil Khare · Accepted Answer

Let the speed of the particle be v when it reaches the origin.Let the charge of point charges be q.Uinitial = (-KQq/5) + (-KQq/5) + (Kq2/6) = (-2KQq/5) + (Kq2/6)Ufinal = (-KQq/3) + (-KQq/3) + (Kq2/6) + (mv2/2) = (-2KQq/3) + (Kq2/6) + (mv2/2)We know that, Uinitial = Ufinal (-2KQq/5) + (Kq2/6) = (-2KQq/3) + (Kq2/6) + (mv2/2) (mv2/2) = (2KQq/3) + (-2KQq/5) (mv2/2) = (4KQq/15) v = (8KQq/15m)½ Thus speed of particle on reaching origin is (8KQq/15m)½.
