Two mutually perpendicular long straight conductors carrying uniformly distributed charges of linear charges densities `lambda_(1)` and `lambda_(2)` are position at a distance a from each other. How does the interaction between the rods depends on a ?

Two parallel infinite line charges with linear charge densities +lambda C//m and -lambda C/m are placed at a distance of 2R in free space. What is the electric field mid-way between the two line charges?

Two infinitely long thin styraight wires having uniform linear charge densities lambda and 2lambda are arranged parallel to each other at a distance r apart.The intensity of the electric field at a point midway between them is

Two infinitely long parallel wires having linear charge densities lambda_(1) and lambda_(2) respectively are placed at a distance of R metres. The force per unit length on either wire will be (k= 1/(4piepsilon_(0)))

Calculate the potential at a point on the perpendicular bisector of uniformly charged thin rod (linear density of charge = lambda ) of length 2l at a distance a from the centre of the rod.

An infinitely long straight conductor carrying a charge with a linear density +T and a point charge -Q are at a certain distance from each other. In which of the three regions (I, II or III) are there points that (a) lie on the line passing through tho point charge perpendicular to the conductor. and (b) at which ..th~ field strength is zero 1)

The electric field intensity due to a thin infinity long straight wire of uniform linear charge density lambda at O is-

Two mutually perpendicular infinite wires along x-axis and y-axis carry charge densities lambda_(1) and lambda_(2) (see figure). The 1 electric line of force at P is along the line y=(1)/(sqrt(3))x , where P is also a point lying on the same line, then find lambda_(1)//lambda_(2)
