A thin insulator rod is placed between two unlike point charges + q, and - q2 . The magnitude of electrostatic force on q, in the absence of the insulator rod is F]. But the magnitude of electrostatic force on q in the presence of the insulator rod is F2, then F1F2??

Question

A thin insulator rod is placed between two unlike point charges + q, and - q2 . The magnitude of electrostatic force on q, in the absence of the insulator rod is F]. But the magnitude of electrostatic force on q in the presence of the insulator rod is F2, then 
F1<F2 OR F1>F2??
