For an infinite line of charge having linear charge density `lambda` lying along x-axis the work done in moving a charge `q` form `C` to `A` along `CA` is

An infinite line of charge lamda per unit length is placed along the y-axis. The work done in moving a charge q from A(a,0) to B (2a,0) is

An infinite line of charge lamda per unit length is placed along the y-axis. The work done in moving a charge q from A(a,0) to B (2a,0) is

Consider an infinite line charge having uniform linear charge density and passing through the axis of a cylinder is removed.

Consider an infinite line charge having uniform linear charge density and passing through the axis of a cylinder is removed.

The electric field at distance .r. from infinte line of charge ("having linear charge density" lambda) is

The are AB with the centre C and infinitely long wire having linear charge density lambda are lying in the same plane. The minium amount of work to be done to move a point charge q_(0) from point A to B through a circular path AB of radius a is equal to
