Two charges `-2Q` abd `Q` are located at the points with coordinates `(-3a, 0)` and `(+3a, 0)` respectively in the x-y plane. (i) Show that all points
Correct Answer - (a) Radius 4a, cantre at `(5a,0)` (b). `V=(Q)/(4piepsilon_(0))[(1)/(|(x-3a)|)-(2)/(|(x+3a)|)]` (c). At `x=9a` where `V=0`, the charged particle eventually crosses the circle `v=sqrt((Qq)/(8piepsilon_(0)ma))`
