Question

an electric dipole consists of 2 opposite charges each of magnitude 2micro coulomb separated by distance 1 cm .The dipole is placed in an external field of 10^3N/C the maximum torque on the diploe ?​

Answer 1

First i will find the dipole moment-

p= q*distance between them

= (2*10^-6)*(2*10^-2)

= 4*10^-8

now in an external electric field(E), maximum torque is T= p*E

= (4*10^-8)*(1000)

= 4*10^-5 Nm

Answer 2

Explanation:

p=2*0.01

torque =p*E=2*0.01*10³=0.02*10³

hope it will help you.
