We introduce an electron in a homogeneous electric field. can we have a net torque on the electron? explain.

  No

Explanation:

As we know that force on charge given as

F = q E

E=Electric filed

F=Force

q=Charge

Torque = Force x Distance between force

For producing torque two charge is required one single charge can not produce torque.So when we placed an electron in homogeneous field then it did not experience any net torque.

So answer is No.

it takes about 30 days for it to break down

the displacement produced by the body.  

the amount of force subjected to the body.  

the angle between the direction of force and displacement
