The potential of a charge `q_(1)` is +10V at the point P .When we bring another charge `q_(2)` ,the potential at P becomes 4V.Then `q_(2)` is

A charge q_(1) = 2.00 mu C is located at the origin , and a charge q_(2) = - 6.00 mu C is located at ( 0,3.00 ) m . (a) Find the total electric potential due to these charges at the point P hose coordinates are ( 4.00,0) m . ( b) Find the change in potential energy of the system of two charges plus a charge q_(3)= 3.00 muC as the latter charge moves from infinity to point P .

The potential energy of a charged conductor of charge (q) and potential (v) is given by

A positive point charge q_(1) is placed at (a,0) and another positive point charge q_(2) is placed at (0,a) . Find the force acting on q_(1) .

The potential difference (V_P - V_Q) between the points P and Q in the part of a circuit as shown in figure is

In the firgure the charge Q is at the centre of the circle. Work done is maximum when another charge is taken from point P to

A battery is used to charge a parallel plate combination of two identical capacitors. If the potential difference across the battery is V and the total charge Q flows through the battery during the charging process then 1) The charge on each capacitor is Q/2 and the potential of each capacitor is V/2 2) The charge on each capacitor is Q and the potential of each capacitor is V 3) The charge on each capacitor is Q/2 and the potential of each capacitor is V 4) The charge on each capacitor is Q and the potential of each capacitor is V/2

In Figure if the potential at Point P is 100 V , what is the potential at point Q?

The potential at a point P' on the axial line of the short dipole on the side of positive charge is 10V. Then the potential at the same point when dipole was reversed will be
