An insulating rod of uniform linear charge density A and uniform linear mass density `mu` lies on a smooth table whose surface is `xy`-plane. A uniform electric field E is switched on in the space:

An insulating rod having linear charge density lambda = 40.0 mu Cm^-1 and linear mass density mu = 0.100 kg m^-1 is released from rest in a uniform electric field E = 100 Vm^(-1) directed perpendicular to the rod. (a) Determine the speed of the rod after it has travelled 2.00 m (b) How does your answer to part (a) change if the electric field is not perpendicular to the rod ?

A ring carries a uniform linear charge density on one half and the linear charge density of same magnitude but opposite sign on the other half.

A uniformly charged non conducting rod is suspended vertically at its end. The rod can swing freely in the vertical plane without any friction. The linear charge density on the rod is lamda C//m and it has a uniformly distributed mass of M Length of the rod is L. A uniform horizontal electrif field (E) is switched on in the region. (a). For what value of electric field (call it E_(0) ) the rod just manages to make itself horizontal.? (b). If eletrif field E_(0) is switched on, what is the maximum angular speed acquired by the rod during its motion?

A square loop of side 'l' having uniform linear charge density ' lambda ' is placed in 'xy' plane as shown in the figure. There is a non uniform electric field vec E= a/l (x+l) hat i where a is a constant. Then resultant electric force on the loop if l=10cm, a=2N//C and charge density lambda = 2muC//m is:

A nonconducting ring of uniform mass m, radius b and uniform linear charge density lambda is suspended as shown in figure in a gravity free space. There is uniform coaxial magnetic field B_0 , pointing up in a circular region of radius 'a' (lt b) . Now if this field is switched off, then:-

Due to which the surface charge density arises on the surface of a dielectric slab, when it is placed in a uniform electric field ?

If the uniform surface charge density on the infinite plane sheet is sigma , electric field near the surface will be
