Question

Write the expression for torque in uniform electric field?​

Answer 1

Derivation of Torque on an Electric Dipole

And the direction of the dipole moment is from the positive to the negative charge; it can be seen from the above equation that the torque is the cross product of the dipole moment and electric field.

please mark as brainlist i need it..

please mark

please

Answer 2

Answer:

(qE)×(2dsinθ)

Explanation:

Torque experienced by the dipole is (qE)×(2dsinθ) where 2d is the length of dipole and zero is the angle between dipole and field direction.
