Question

write the formula for magnet of torque you what is the torque you went theta is equal to 180 degree​

Answer 1

Answer:

The measure of force that induces an object to rotate around an axis is called torque. A Torque is a number of vectors and its path depends on the direction of the force on the axis. Torque is given by the formula

τ = pE sinθ

Potential energy (U) of the system is given as

Potential energy (U) of the system is given asU = -pE cosθ …………………….(2)

Potential energy (U) of the system is given asU = -pE cosθ …………………….(2)In uniform electric field net force on

Potential energy (U) of the system is given asU = -pE cosθ …………………….(2)In uniform electric field net force on(1) Torque can be zero only if θ is 00 or π0.

Potential energy (U) of the system is given asU = -pE cosθ …………………….(2)In uniform electric field net force on(1) Torque can be zero only if θ is 00 or π0.(2) Dipole moment is always zero.

A dipole in stable equilibrium, when Electric filed and dipole moment are perpendicular to each other i.e. the angle between them is zero degrees and torque will be maximum.
