A thread carrying a unifrom charge `lambda` per unit length has the configuration shown in fig,

Each of the two long parallel threads carries a uniform charge lambda per unit length. The threads are separated by a distance l . Find the maximum magnitude of the electric firld strength in the symmetry plane of theis system located between the threads.

A thin infinitely long thread carrying a charge lambda per unit length is oriented parallel to the infinite conducting plane. The distance between the thread and the plane is equal to l . Find : (a) the moducles of the vector of the force acting on a unit length of the thread , (b) the disribution of surface chagre density sigma (x) over the plane, where x is the distance form the plane perpendicular to the conducting surface and passing through the thread.

A long wire with a uniform charge density lambda is bent in two configurations shown in fig. Determine the electric field intensity at point O.

A very long straight uniformly charged thread carries a charge lambda per unit length. Find the magnitude and direaction of the electric field strength at point which is at a distance y from the thread and lies on the perpendicular passing through one of the thread's ends.

Find the focal length of the lens shown in Fig.

Two long, thin, parallel conductors are kept very close to each other, without touching. One carries a current i and the other has charge lambda , per unit length. An electron moving parallel to the conductor is undeflected. Let c = velocity of right (i) v = (lambda c^(2))/(i) (ii) v = (i)/(lambda) (iii) c = (i)/(lambda) (iv) the electron may be at any distance from the conductor
