1.

When will be the torque acting on the electric dipole is maximum.

Answer»

Formula, of Torque = PEsin∅

where P is dipole moment

E is electric field

and ∅ is the angle dipole and Electric field .

Now,

T = PEsin∅

Torque maximum when , sin∅→ max

We know max value of sin∅ = 1 at ∅ = π/2

So, max T = P.E
