SUMMARY
A point charge "e" placed near a spherical conductor with radius "a" and charge "q" will experience repulsion unless it is positioned within a distance of less than (a/2) * √(e/q) from the nearest point on the conductor's surface. This conclusion is derived from the principles of electrostatics and the behavior of electric fields around conductors. The repulsion occurs due to the redistribution of charge on the conductor's surface in response to the external point charge.
