A charge 6 muC is placed at the origin and another charge -5 muC is placed on the Y-axis at position A(0,6,1)m:- Calculate the work done to bring a proton from infinity to the point P.

A charge 6 muC is placed at the origin and another charge -5 muC is placed on the Y-axis at position A(0,6,0)m. Calculate the total electric potential at the point P whose coordinates are (8, 0, 0) m.

The work done in bringing a unit positive charge from infinity to the given point against the direction of electric intensity is

Potential at a point A in space is given as 4 xx 10^5V :- Find the work done in bringing a charge of 3muC from infinity to the point A.

Two point charges + 0.2muC and 0.01muC are placed 10cm apart. Calculate the work done in reducing the distance 5cm between them.

The length of a straight thin wire is 2 m. It is uniformly charged with a positive charge of 3 C. If charge density of the wire is 1.5 x 10-6 C/m then calculate the electric intensity due to the wire at a point 1.5 m away from the centre of the wire.

Charge +q and -q are placed at points A and B respectively which are distance 2 L apart . C is the mid point of A and B . The work done in moving a charge +Q along the semicircle CRD as shown in the figure below is

Two point charges of + 5 mu C are so placed that they experience a force of 8 xx 10^-3 N. They are then moved apart, so that the force is now 2 xx 10^-3 N. The distance between them is now
