Question

An electric dipole moment p is placed in an electric field of intensity 'E'. The dipole acquires a position such that the axis of the dipole makes an angle theta with the direction of the field. Assuming that the potential energy of the dipole to be zero when theta= 90^(@), the torque and the potential energy of the dipole will respectively be

Answer 2

Answer:

mark me brainliest

Explanation:

Potential energy of the dipole

U=−∫TdB

U=−∫ PEsinθdθ

from π/2 to θ

​U=PE(cosθ−0)=−PEcosθ

and

torque =PEsinθ
