If "`q_(1)+q_(2)=q`" ,then the value of the ratio "`q_(1)/q`" ,for which the force between `q_(1)` and "`q_(2)`" is maximum is

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 charged paricles are placed on a straight line as shown in fig. q_(1) and q_(2) are fixed but q_(3) can be moved. Under the action of the forces from q_(1),q_(2) and q_(3) is in equilbrium. What is the relation between q_(1) and q_(2) .

The value of charge q_1 ,q_2 and q_3 as shown in the figure are

Three equal charges are placed on the three corners of a square. If the force between q_(1) and q_(2) is F_(12) and that between q_(1) and q_(3) is F_(13) , then the ratio of magnitudes (F_(12)//F_(13)) is

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)

Threee charges +Q_(1),+Q_(2) and q are placed on a straight line such that q is somewhere in between +Q_(1) and Q_(2) . If this system of charges is in equlibirium what should be the magnitude and sign of charge q?

Three charges are placed as shown in fig. the magnitude of q1 is 2.00mu C , but its sign and the value of the charge q_(3) is +4.00muC , and the net force on q_(3) is entirely in the negative x-direction As per the condition given in the problem, the sign of q_(1) and q_(2) will be

Looking at the various electric lines of forces between charges Q_(1) and Q_(2) , find the value of (Q_(1))/(Q_(2))

Calculate Q_(1),Q_(2)and Q_(3),
