When electric dipole is placed in a uniform electric field

the dipole experiences torque.

Torque experienced by the dipole in uniform electric field=PEsin=PEsin



(i) For minimum torque=0=0



T =PEsin0



=0



(ii) For maximum torque=90=90



max=PEsin90



=PE

Shivam,

You can ask career related questions here. Although I'm not going to disappoint you with this question too, but you should write the completed question isn't it?

Angle between dipole moment and electrical field for maximum torque is 90 degree and for minimum torque is 0 degree. We can explain like Torque= pE sin(theta). So max and min torque totally depends upon the value of theta. Consider modular maximum value of sine (1) and modular minum value of sine (0)

Hope it'll help you
