Class 12 NEET Physics Electrostatics Questions Part 1

Dipole moment of the dipole p and uniform Electric field E.
we know that dipole moment p= qa (where q is charge and a is the dipole length).
when a dipole of Dipole moment p is placed in a uniform Electric field E,
the torque τ= Either force × perpendicular distance between the two forces =qaE‌sin‌θ or τ=pEsinθ or τ=p×E
