1. What must be the relationship between the value of RL and RC if the
network shown below is to be resonant at all frequencies?
2. Two equal spheres, each of mass m are in contact on a smooth horizontal
table, a third identical sphere impinges symmetrically on them if this sphere is
reduced to rest by the impact, then
(a) e = 1/3
(b) e = 1/4
(c) e = 2/3
(d) e = 3/4
3. For the system of connected bodies the initial angular
velocity of the compound pulley B is 6 rad per sec counter clockwise and weight
D is decelerating at the constant rate of 4 cm/s2 . What distance
will weight A travel before coming to rest?
(a) 6.5 cm
(b) 9.5 cm
(c) 11.5 cm
(d) 13.5 cm
4. A circular board of mass M and radius a is placed on a smooth
horizontal plane, and a body of mass m runs round the edge of it at a uniform
rate. See the following statements:
[A] Centre of disc describes a circle around the centre of mass G of the
system (body + board) as centre and GO as radius. [B] Centre of mass G of the
system (body + board) describes a circle with O as centre and GO as radius.
(a) A is correct, B is wrong
(b) A is wrong, B is correct
(c) Both A and B are wrong
(d) Both A and B are correct
5. A conductor 1 cm in length is parallel to z axis and rotates at a
radius of 25 cm at 1200 rev/min. The induced voltage across the conductor if the
radial field is given by B = 0.5 T is
