Question

An electric dipole placed in a uniform electric field of magnitude 2 N/C, experiences a maximum torque of magnitude 5 x 10-3 N m. If the charges of the dipole have a magnitude of 2 mC. then the length of the dipole is ​

Answer 1

Answer:

hope it's helpful marks me at brainlist

Explanation:

Electric dipole moment, E=4×10−9N/C

Angle made by p with a uniform electric field, θ = 30°

Electric field, E=5×104N/C

Torque acting

on the dipole:

 τ=pEsinθ

=4×10−9×5×104×sin30o

=20×10−5×21

=10−4Nm

Hence, the magnitude of the torque acting on the dipole is 10−4 N m.
