Question

no torque is produce when angle theta = 180° .how can someone explain it for plz

Answer 1

That is too simple.

Torque is a force that tend to cause rotation.

When the angle is 180 it means that no angle is created instead of straight line

Answer 2

we know that torque = PE sin Ф.where P represents dipole and E represents electric field.

                       so when Ф= 180 implies that sinФ = sin 180 = 0.

                        therefore toque becomes zero.so therefore no torque is produced.


hope in a way it is useful!
