Question
Three points charges are placed at the corners of an equilateral triangle of side L as shown in the figure :
Options
A.The potential at the centroid of the triangle is zero.
B.The electric field at the centroid of the triangle is zero.
C.The dipole moment of the system is √2 qL
D.The dipole moment of the system is √3 qL
Solution
Potential at centroid of ᐃ
=
Dipole moment of system
= 2p cos 30o = √3p
= √3 × q × L
(∴ p = q × L)
=
Dipole moment of system
= 2p cos 30o = √3p
= √3 × q × L
(∴ p = q × L)
