What orientation of the dipole has the greatest electric potential energy? what orientation of the dipole has the greatest electric potential energy? when the dipole moment and the electric field are antiparallel when the dipole moment and the electric field are parallel when the dipole moment makes the 60∘ angle with the electric field when the dipole moment and the electric field are perpendicular

a.

Explanation:

The orientation of the dipole has the greatest electric potential energy is when when the dipole moment and the electric field are anti parallel to each other at that time cosθ= -1

U = -pEcosθ

put θ=180

⇒cos180 = -1

Therefore, U = pE

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.
