Yes, when the charge on one body Q is much greater than that on the other q and they are close enough to each other so that force of attraction between Q and induced charge on the other exceeds the force of repulsion between Q and q.
However, two similar point charges can never attract each other because no induction will take place here.

Reynolds Number
Last modified on:3 years agoReading Time:10MinutesWhat is Reynolds Number? The Reynolds number (Re) is a dimensionless parameter used in fluid mechanics to characterize the flow of a fluid (liquid or gas) around an object or through a conduit. It relates the inertial forces to the viscous forces in the fluid and helps determine the type of…

Conceptual Questions Based on Class 12 Physics Alternating Current
Last modified on:4 years agoReading Time:11MinutesConceptual Questions Based on Alternating Current Q.1. Why a d.c. voltmeter and d.c. ammeter cannot read a.c.? Solution. The average value of a.c. over a cycle is zero. So, a d.c. voltmeter/ammeter will show zero reading with alternating voltage/current. Q.2. What is meant by the statement that the current through an…

Conceptual Questions Based on Electromagnetic Induction
Last modified on:4 years agoReading Time:7MinutesQ.1. Will an induced emf develop in a conductor, when moved in a direction parallel to the magnetic field ? Solution. No, because the magnetic flux linked with the conductor does not change when it is moved parallel to the magnetic field. Moreover, the magnetic Lorentz force on the free electrons…
