You have two rods a and b, both made of a nonconducting material. initially, neither rod is charged. a sphere carrying 100 units of surplus positive charge is placed close to the left end of rod a. one end of rod b is touched to the right end of rod a for some time interval and then removed.

what is the final charge on rod b?

a) the charge is zero.

b) the charge is negative. t

c) the charge is positive.

a) The charge is zero.

Explanation:

Given that we have two rods of non conducting material.

Another sphere having 100 units of positive charge is when placed close to the left end of the one of the rod A will induce a negative charge on the atoms of the rod nearest to the sphere but the charge cannot be transmitted to the whole bulk material of the rod as it is made up of a nonconducting material. Therefore, there will be no effect on the other end of the rod A and hence on bringing the rod B in contact to the right end of the rod A the rod B will still remain electrically neutral in charge.

The answer is b hope this
