A charge q_(1) exerts some force on a second charge q_(2) If a third charge q_(3) is brought near q_(2) , then the force exterted by q_(1) on q_(2)

Assertion(A): A charge q_(1) exerts some force on a second charge q_(2) .If a third charge q_(3) is brought near,the force exerted by q_(1) and q_(2) does not change. Reason (R ) :No work is done tomove a charge on an equipotential line or surface.

A charge Q_1 exerts some force on a second charge Q_2 . If a 3rd charge Q_3 is brought near, the force of Q_1 exerted on Q_2 :-

A charge Q exerts a 12 N force on another charge q. If the distance between the charges is doubled, what is the magnitude of the force exerted on Q by q?

Assertion: Two charges q_(1) and q_(2) are placed at separation r . Then magnitude of the force on each charge is F . Reason: Now a third charge q_(3) is placed near q_(1) and q_(2) . Then force on q_(1) and q_(2) remains F .

When two charges q_(1) and q_(2) are kept at some distance apart, force acting between these charges is F. If a third change q_(3) is placed quite close to q_(3) is placed quite close to q_(2) what will happen to the force between q_(1) and q_(2) ?

Three charges q_(1) = 1 mu C, q_(2) = -2 muC and q_(3) = 3mu C are placed on the vertices of an equilateral triangle of side 1.0 m. find the net electric force acting on charge q_(1) . How to proceed Charge q_(2) will attract charge q_(1) (along the line joining them) and charge q_(3) will repel charge q_(1) . Therefore, two forces will act on q_(1) , one due to q_(2) and another due to q_(3) . Since , the force is a vector quantity both of these force (say F_(1) and F_(2) ) will be added by vector method. Following are two methods of their addition

A particle of mass m and carrying charge -q_(1) is moving around a charge +q_(2) along a circular path of radius r period of revolution of the charge -q_(1) about +q_(2) is

A particle of mass m carrying a charge -q_(1) starts moving around a fixed charge +q_(2) along a circulare path of radius r. Find the time period of revolution T of charge -q_(1) .
