Question

​​​​​​​HELP PLEASE!

Problem 4 Select the answer which corresponds to the statements below. A negatively charged glass rod repels an object suspended by a non-conducting thread. The charge on the object is Two neutral metal spheres, #1 and #2, are mounted on insulating supports. They are connected by a wire. A positively charged glass rod is brought near sphere #1 . The wire connecting the spheres is removed and the charged rod is then taken away. Now the charge on sphere #2 is . A positively charged glass rod attracts an object suspended by a non-conducting thread. The charge on the object is A positively charged ball is brought close to a neutral isolated conductor. The conductor is then grounded, while the ball is kept close. If the ground connection is first removed and then the ball is taken away, the conductor has a charge. B Two neutral metal spheres, #1 and #2, are mounted on insulating supports. They are connected by a wire, and a second wire connects them to ground. A positively charged glass rod is brought near sphere #1 . The ground wire is removed and the rod is taken away. Then the wire connecting the spheres is taken away. The charge on sphere #1 is now

Answer 1

Solution)

1) Negative , Since, charges are repelled when they have same magnitude.The glass rod is negative so the object will also be Negative.

====

2) Positive since the electrons will flow out of sphere 2 into sphere 1 as they are attracted to the positively charged rod. When wire is removed Sphere 1 will be Negative and Sphere 2 will acquire Positive charge.

======

3) Negative

Since the positively charged ball will cause the neutral conductor to become negatively charged. Electrons will flow from the ground into the conductor making it Negative.
