An electric dipole moment vec(p)=(2.0hat(i)+3.0hat(j))muC m is placed in a uniform electric fiel vec(E)=(3.0hat(i)+2.0hat(k))xx10^(5)NC^(-1).

Answer»

The torque that `vec (E )` exerts on `vec(P)` is `(0.6 hat(i) - 0.4hat(j) - 0.9 hat(K))` Nm.
The potential ENERGY of the DIPOLE is - 0.6 j.
The potential energy of the dipole is 0.6 j.
If the dipole is rotated in the electric field, the MAXIMUM potential energy of the dipole is1.3j.
