A positively charged insulator is brought near(but does not touch) two metallic sphere that are in contact. The metallic spheres are then separated. The sphere which was initially farthest from the insulator will have:

Options

A. no net charge
B. a negative charge
C. a positive charge
D. either a negative or a positive charge.

Answer

C

Explanation

The positively charged insulator pulls the free electron in sphere towards left till electrostatic equilibrium is reached. Hence if both sphere are now separated the sphere `II` has deficiency of electrons, i.e., it has Positive charge
