One end of a horizontal thick copper wire of length 2L and radius 2R is welded to an end fo another horizontal thin copper wire of lenth L and radius R. When the arrangement is stretched by applying forces at two ends, the ratio of the elongation in the thin wire to that in the thick wire is

Wires A and B are made from the same material. A has twice the diameter and three times the length of B . If the elastic limits are not reached, when each is stretched by the same tension, the ratio of energy stored in A to that in B is

Two bodies of unequal mass are moving in the same direction with equal kinetic energy .The two bodies are brought to rest by applying regarding force of same magnitude . How would the distance moved by them before coming to rest compare ?

Figure 14.26 (a) shows a spring of force constant k clamped rigidly at one end and a mass m attached to its free end. A force F applied at the free end stretches the spring. Figure 14.26 (b) shows the same spring with both ends free and attached to a mass m at either end. Each end of the spring in Fig. 14.26(b) is stretched by the same force F. If the mass in Fig. (a) and the two masses in Fig. (b) are released, what is the period of oscillation in each case ?

The sum of the magnitudes of two forces acting at a point is 16 N. The resultant of these forces is perpendicular to the smaller force has a magnitude of 8 N. If the smaller force is magnitude x, then the value of x is (A) 2N (B) 4N (C) 6N (D) 7N

Two quantities A and B are related by A//B=m where m is linear mass density and A is force. The dimensions of B will be same as that of-

Figure 14.26 (a) shows a spring of force constant k clamped rigidly at one end and a mass m attached to its free end. A force F applied at the free end stretches the spring. Figure 14.26 (b) shows the same spring with both ends free and attached to a mass m at either end. Each end of the spring in Fig. 14.26(b) is stretched by the same force F. What is the maximum extension of the spring in the two cases ?

A: A thread of length L is streatched by a force of 5N, its length increases by a and stretched by force of 6N its length increases by b, now if it is stretched by force of 11 N its length increases by (a + b -L). R: Increasing the length of elastic thread is proportional to its initial length.

Two similar springs P and Q have spring constant k_(p) and k_(Q) such that k_(p) gt k_(Q) . They are stretched , first by the same amount (case a,) then by the same force (case b ) . The work done by the springs W_(P) and W_(Q) are related as , in case (a) and case (b) , respectively :
