calculate potential energy when a point charge Q is placed on the equa

1.	calculate potential energy when a point charge Q is placed on the equator of a short dipole of dipole moment p at a distance of r from it
Answer» electric potential energy WOULD be zero we have to calculate potential energy when a point CHARGE Q is placed on the EQUATOR of a short DIPOLE of dipole moment P at a distance r from it. we know, potential energy , U = charge × potential difference. electric potential at a point on equatorial line of a dipole P, V = Kpcos90°/r² = 0 [ in case of equatorial line, angle between dipole moment and r is 90° ] distance of charge from the point on equatorial plane remains constant. so, potential difference on equatorial line , ∆V = 0 so, electric potential energy, U = Q × 0 = 0 therefore, electric potential energy would be zero

Answer»

electric potential energy WOULD be zero

we have to calculate potential energy when a point CHARGE Q is placed on the EQUATOR of a short DIPOLE of dipole moment P at a distance r from it.

we know, potential energy , U = charge × potential difference.

electric potential at a point on equatorial line of a dipole P, V = Kpcos90°/r² = 0

[ in case of equatorial line, angle between dipole moment and r is 90° ]

distance of charge from the point on equatorial plane remains constant. so, potential difference on equatorial line , ∆V = 0

so, electric potential energy, U = Q × 0

= 0

therefore, electric potential energy would be zero
