Pls answer and show work thx

1. As shown in the diagram, a neutral pith ball suspended on a string is attracted to a positively charged rod. During contact with the rod, the pith ball Pith Ball a. loses electrons + + + + + b. gains electrons c. loses protons Rod d. gains protons 2. As a positively charged rod is brought near to but not allowed to touch the knob of an uncharged electroscope, the leaves will diverge because a. negative charges are transferred from the electroscope to the rod b. negative charges are attracted to the knob of the electroscope c. positive charges are repelled to the leaves of the electroscope d. positive charges are transferred from the rod to the electroscope 3. As shown in the diagram below, a charged rod is held near, but not touching, a neutral electroscope. .+ + + ++ +++ The charge on the knob is KNOB a. positive and the leaves are positive b. negative and the leaves are negative c. negative and the leaves are positive d. positive and the leaves are negative 4. A positively charged object was used to give an electroscope a negative charge. The electroscope was charged by . Give a description of the electron flow
