Thetop of the atmosphere is at about 400kV with respect to the surface of the earth , corresponding to an electric field that decreases with altitude. Near the surface of the earth, the field is about 100Vm^(-1). Why then do we not our house into the open? (Assume the house to be a steel cage so there is no field inside)

1.	Thetop of the atmosphere is at about 400kV with respect to the surface of the earth , corresponding to an electric field that decreases with altitude. Near the surface of the earth, the field is about 100Vm^(-1). Why then do we not our house into the open? (Assume the house to be a steel cage so there is no field inside)
Answer» Solution :Since our body and the surface of EARTH both are conducting therefore and equipotential surface. As we STEP out into the open from our house the original equipotential SURFACES of open air CHANGE, keeping out body and the ground at the same potential that is why we donot GET an electric shock.

A wire is bent to form a semicircle of the radius a. The wire rotates about its one end with angular velocity omega . Axis of rotation is perpendicular to the plane of the semicircle . In the space , a uniform magnetic field of induction B exists along the aixs of rotation as shown in the figure . Then -
A massless non conducting rod AB of length 2l is placed in uniform time varying magnetic field confined in a cylindrical region of radius (R gt l) as shown in the figure. The center of the rod coincides with the centre of the cylin- drical region. The rod can freely rotate in the plane of the Figure about an axis coinciding with the axis of the cylinder. Two particles, each of mass m and charge q are attached to the ends A and B of the rod. The time varying magnetic field in this cylindrical region is given by B = B_(0) [1-(t)/(2)] where B_(0) is a constant. The field is switched on at time t = 0. Consider B_(0) = 100T, l = 4 cm(q)/(m) = (4pi)/(100) C//kg. Calculate the time in which the rod will reach position CD shown in the figure for th first time. Will end A be at C or D at this instant ?
