The potential (in volts) of a charge distribution is given by V(z)=30-5z^(2) for |z|le1m V(z)=35-10|z| for |z|ge1m V(z) does not depend on x and y. If this potential is generated by a constant charge per unit volume rho_(0) (in units of epsilon_(0)) which is spread over a certain regiion, then choose the correct statement.

The potential (in volts) of a charge distribution is given by V(z)=30

1.	The potential (in volts) of a charge distribution is given by V(z)=30-5z^(2) for \|z\|le1m V(z)=35-10\|z\| for \|z\|ge1m V(z) does not depend on x and y. If this potential is generated by a constant charge per unit volume rho_(0) (in units of epsilon_(0)) which is spread over a certain regiion, then choose the correct statement.
Answer» <P>`rho_(0)=20 epsilon_(0)` is the entire region `rho_(0)=10 epsilon_(0)` for `\|z\|le1` m and `p_(0)=0` elsewhere `rho_(0)=20 epsilon_(0)`for `\|z\|le 1` m and `p_(0)=0` else where `rho_(0)=4o epsilon_(0)` in the entire region Answer :B

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 ?
