_ The ligu re to the right shows two infinite planes of charge. The IeFt plane has charge density in = +30. The right plane has uniform surface charge densitg.r o", = :1'. Compute the electric eld at P if a = H.03mpCIm2 Select ne ofthe Following: ProhIEm 4.19 lCan a charged object exert a Force on an uncharged insulator? If 35, why; Select lCline of the Following: [a] 1'I"es. by inducing an electrical polarization in the insulator; the insulator is then attracted to the charged object. {b} 1'I"es. by inducing an electrical polarization in the insulator; the insulator is then repelled by the charged object. {c} No, because uncharged objects do not feel electrical forces. (d) No, because only:I conductors are attracted to or repelled by charged objecls. {e} No, because an insulator does not permit the motion of electric charge
