In the following question, a statement of Assertion is followed by a statement of Reason. Mark the correct choice. Assertion: In an elastic collision of two billiard balls are in contact with each other. During the short time of collision, kinetic energy is conserved. Reason: Energy, spent against friction does not follow the law of conservation of energy

Figure shows the intensity-wavelength relations of X-rays coming from two different Coolidge tube. The solid curve represents the relation for the tube A in which the potential difference between the target and the filament is V_a and the atomic number of the target material is Z_A . These quantities are V_beta and Z_beta for the other tube. Then,

Two balls having masses m and 2m are fasrtened to two light strings of same length (figure). The other ends of the strings are fixed at O. The strings are kept in the same horizontal line and the system is released from rest. The collision between the balls is elastic. Point A is the lowest point at which either ball can reach The speed of ball of mass 2m just after collision (for the first time) is over

Two identical coils, each with N turns and radius R are Placed coaxially at a distance R as shown in the figure. If I is the current passing through the loops in the same direction, then the magnetic field at a point P which is at exactly at (R )/(2) distance between two coils is ........... .

Two small balls A and B each of mass m, are joined rigidly to the ends of a light rod of length L figure. The system translates on a frictionless horizontal surface with a velocity v_0 in a direction perpendicular to the rod. A particle P of mass kept at rest on the surface sticks to the ball A as the ball collides with it . Find a. the linear speeds of the balls A and B after the collision, b. the velocity of the centre of mass C of the system A+B+P and c. the angular speed of the system about C after the collision.
