In a certain regionof space electric fieldis along the z direction throughuot the magnitude of electricis however not constant10^(-5) NC^(-1)per meter what are the forcetorque experienced by a system having a total dipole 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
