Question

An experiment is performed involving a negatively charged rod and a conducting
sphere, which is suspended from a support by an insulated thread. Listed below are
procedures demonstrating the methods of charging of objects and possible observations

I. the negatively charged rod is brought
near the conducting sphere
l. the conducting sphere is first attracted
to the neqatively charged rod

II. the conducting sphere is touched by the
negatively charged rod
ll. the conducting sphere is then repelled
by the negatively charged rod

1. Refer to the above experiment. As the negatively charged rod is brought near the conducting sphere, the observation that the conducting sphere is first attracted to the charged rod is because the side of the sphere,
closest to the rod, has become charged:
a. positively by conduction c. positively by induction
b. negatively by conduction d. negatively by induction

2. Refer to the above electrostatic experiment. As the conducting sphere is touched by the negatively charged rod, the observation that the conducting sphere is then repelled by the charged rod is because the side of the sphere, closest to the rod, has become charged:
a. positively by conduction c. positively by induction
b. negatively by conduction d. negatively by induction


(I answer 1c and 2d, is this correct)

Explanation / Answer

1 c. positively by induction positive charges are generated on side of sphere near the conducting sphere 2 b. negatively by conduction negative charges move form rod to sphere making negatively charged
