Three charges +q, +q, +2q are arranged as shown in figure. What is the field at point P (center of side AC)

Assertion (A): Three point charges Q_(1), Q_(2) and Q_(3) are shown in the figure. The flux over the Gaussian surface depends on only one charge point. Reason (R): Electric flux depends on the all charges nearby.

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

In an isolated parallel plate capacitor of capacitance C the four surfaces have charges Q_(1), Q_(2), Q_(3) and Q_(4) as shown in the figure. The potential difference between the plates is :

Conisder a system of three charges q//3 , q//3 and -2q//3 placed at point A, B and C, respectively, as shown in the figure. Take O to be centre of the circle of radius R and angle CAB=60^@

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 .

Two points charge q_(1) and q_(2)(=q_(1)//2) are placed at points A(0,1) and B(1,0) as shown in the figure.The electric field vector at point P(1,1) makes an angle q with the x-axis ,then the angle q is
