Question

Problem Select the answer which corresponds to the statements below A positively 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 ey are connected by a me. A postres charged glass ro is brought near spheres emre connecting the spheres s r more、ndt echa ge d 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 Two neutral metal spheres, #1 and #2 are mounted on insulating supports. They are connected by a wire and a second w e con ects them to gou A positive y c a ged g ass 10 is rought near s ere札 e ground wres removed and the rod is taken away. Then the wire connecting the spheres is taken away. The charge on sphere #1 is now A positively changed ball is brought close to a neutral isolated conductor The conductor is then grounded, while the ball is kept close. If the ball is first taken away and then the ground conmection is temoved, the comductor has a charge

Answer 1

a) A positively charged glass rod repels an object suspended by a non-conducting thread. The charge on the object is _____.

Answer: Positive

b) 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 sphere is removed and the charged rod is then taken away. Now the charge on sphere #2 is ______.

Answer: Positive

c) A positively charged glass rod attracts an object suspended by a non-conducting thread. The charge on the object is _____.

Answer: Cannot be determined

d) 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 a 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 sphere is taken away.. The charge on sphere #1 is now _____.

Answer: Positive

e) A positively charged ball is brought close to a neutral conductor. the conductor is then grounded, while the ball is kept close. If the ball is first taken away and then the ground connection is removed, the conductor has a ____ charged.

Answer: Neutral
