In a certain region of space, electric field is along the z-direction throughout. The magnitude of electric field is, however, not constant but increases uniformly along the positive z- direction, at the rate of 10^5 NC^(-1) per metre. What are the force and torque experienced by a system having a total dipole moment equal to 10^(-7) Cm in the negative Z-direction? |
| Answer» Solution :Only (C ) is RIGHT the rest cannot REPRESENT electrostaicfield lines (a) is wrong becausefield lines must be NORMAL to a conlductor (B) is wrong because field lines cannot startwrong becauseelectrostaticfield lines cannotform closed loops | |
