   2. Two neutral metal spheres 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 1 is ____ .
   3. A positively charged glass rod attracts an object suspended by a non-conducting thread. The charge on the object is ____ .
   4. A positively charged glass rod repels an object suspended by a non-conducting thread. The charge on the object is ____ .
   5. 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.
   6. A positive point charge is brought near the outside surface of a neutral conducting sphere and released. The initial position of the point charge is on the positive x axis and the sphere is centred on the origin. The point charge moves in the ____ x direction. (If the point charge does not move, select answer C.)

Answer 1

2.B. Migration of electrons starts from sphere B to A.making B positively charged and A negatively charged.when wire is removed B will be evenly distributed with positive charge and A will be accumulated with negative charge at its left side.when glass rod is removed the sphere will be evenly distributed with negative charge.

3.B unlike charges attracts each other.
