please answer all questions.1
A negatively charged plastic rod is brought near a neutral metal can without touching. Will the can be attracted, repelled or unaffected by the rod and why? Attracted. The can becomes positively charged. Unaffected. The can cannot be attracted or repelled since it has no net charge. Attracted. The can is neutral but the part of the can closest to the rod becomes positive and the part furthest away becomes negative. Repelled. The can becomes negatively charged. Attracted. The can is neutral but the part of the can closest to the rod becomes negative and the part furthest away becomes positive.
Three charges are arranged on a line along the x axis with positive charge +3Q at the origin, negative charge -Q at x =2L, and an unknown charge q at x = 7L. The net electric force on the -Q charge is zero. What is q? O 1470/4 -15Q/2 15Q/2 None of the other answers are correct. -75Q/4 -147Q/4 75Q/4
