If the dipole moment vector[IMAGE] of a dipole
and the electric field[IMAGE] (uniform) are oriented as
shown then which of the following statement is incorrect?
Show answer and solution
[IMAGE] where α is always the shorter angle
between[IMAGE] and [IMAGE] ∴ in both cases I and II, α = π − θ ⇒ (cos α)_I = (cos α)_II
∴ U_I = U_II ⇒ (B) is wrong.
(C) and (D) are correct as direction of [IMAGE]
between[IMAGE] and [IMAGE] ∴ in both cases I and II, α = π − θ ⇒ (cos α)_I = (cos α)_II
∴ U_I = U_II ⇒ (B) is wrong.
(C) and (D) are correct as direction of [IMAGE]
