Question

Obtain an expression for the torque acting on dipole placed in a uniform electric field .what is the magnitude of the total force in the electric field

Answer 1

Answer:

hey

Explanation:

Torque:

The measure of force that causes an object to rotate about an axis is known as torque. Torque is a vector quantity and its direction depends on the direction of the force on the axis. The magnitude of the torque vector is calculated as follows:

τ=FrsinΘ  

where r is the length of the moment arm, and θ is the angle between the moment arm and the force vector.

Electric dipole:

A pair of electric charges with an equal magnitude but opposite charges separated by a distance d is known as an electric dipole. The electric dipole moment for this is defined as the product of the magnitude of these charges and the distance between them. The electric dipole moment is a vector having a defined direction from the negative charge to the positive charge.
