उत्तर
Electrostatic induction is the process of charging a body by bringing another charged body near to it. When the X will come near to body B, the opposite charge will be acquired by body B.
So, a negative charge will be acquired. Similarly, by electrostatic induction, A will acquire the opposite charge of B. so A will acquire a positive charge.
