Question

Clearly explain how you arrive at your answer. You will get no score without showing your work or to make an uncharged object have a negative charge, we must Add some atoms Remove some atoms Add some electrons Remove some electrons None of these Two small charged objects repel each other with a force F where separated by a distance d. If the charge on each object is doubled from its original value, the electric force becomes: 4F 16F F/4 F/16 None of the above an isolated point charge produce an electric field with magnitude E at a point 2m away. A point at which the electric field magnitude is E/4 is: 4 m away 8 m away I'm away 0.5 m away None of these A hollow conductor is positively charged A small uncharged metal ball is lowered by a silk thread (insulating material) through a small opening in the top of the conductor and allowed to touch its inner surface. After the ball is removed, it will have: A positive charge A negative charge A charge whose sign depends on where the small bowl is located in the conductor A charge whose sign depends on what part of the inner surface it touched No appreciable charge A point charge is placed at the center of a spherical Gaussian surface. The electric flux is changed if the sphere is replaced by a cube of the same volume if the sphere is replaced by a cube of one-tenth the volume if the point charge is moved off center, but still inside the original sphere if a second point charge is placed just outside the sphere if the point charge is moved to just outside the sphere

Explanation / Answer

1)(C)Add some electrons

(2)(A)4F

F1 = kq1q2/r^2

F2 = k(2q1)(2q2)/r^2 = 4kq1q2/r^2

F2/F1 =4 => F2 = 4F1

(3)(A)4 m away

E = kq/2^2 = kq/4

E/4 = kq/x^2

comaring the two eqn we get

x = 4 m

(4)
(B)Negative charge

It will gain the negative charge due to induction.
