A dipole of dipole moment vec(P) = P_(o) hat(j) is placed at point (l,0). There exists an electric field vec(E)=2ax^(2)hat(i)+(2by^(2)+2cy)hat(j). Then

Answer»

<P>force on dipole is `2rho_(c )hat(J)`
force on dipole is `p(2c + 4bl)hat(j)`
Torque on dipole about its centroidal axis is `2rho_(0)ahat(k)`
Torque on dipole about its centroidal axis is ZERO
