Questions
If a dipole of dipole moment
a
τ→=p→.E→
b
τ→=p→×E→
c
τ→=p→+E→
d
τ→=p→−E→
detailed solution
Correct option is B
Given: Dipole moment of the dipole =p→ and uniform electric field =E→. We know that dipole moment (p)=q.a (where q is the charge and a is dipole length). And when a dipole of dipole moment p→ is placed in uniform electric field E→, the Torque (t) = Either force x perpendicular distance bet ween the two forces =qa esinθ or τ=pEsinθ or τ→=p→×E→ (vector form)Talk to our academic expert!
