Question

A positive charge of 10-6 coulomb is placed
on a solid conducting sphere that is mounted
on an insulating post.
+
What is true?
1. The charge resides uniformly throughout
the sphere.
2. The electric field in the region surround-
ing the sphere increases with increasing dis-
tance from the sphere.
3. When a second conducting sphere is
connected by a conducting wire to the first
sphere, charge is transferred until the electric
potentials of the two spheres are equal.
4. An insulated metal object acquires a net
positive charge when brought near to, but not
in contact with, the sphere.
5. The electric field inside the sphere is con-
stant in magnitude, but not zero.

Explanation / Answer

1 . false , the charge doesnt reside uniformly throughout sphere , it remains uniformly on surface ;

2 . false , the electric field decreses with distance

3 . true , this statement is true

4 . false , it ccannot acquire a net positive charge unless and untill is touched to charged sphere , what it acqiures is induced charge when brought closer ;

5 . false , the electric field inside a conductor is always zero ,
